Thirty six patients attending hospital out-patient breast cancer clinics in Lahore, Pakistan and London. UK were recruited to the study. Women were predominantly married, 20-76 years of age with an average of three children. Semi-structured interviews were undertaken.

Interview data were analysed using thematic analysis.

Results: Five themes emerged: Discovery and reaction to the disease; disclosure to family; Galunisertib supplier developing emotions; emerging reality: long term uncertainty.

Conclusions: Data infer that irrespective of city of residence, the cultural attributes of women, breast health awareness and reactions to the diagnosis and treatment are similar. To raise awareness, more focused health education interventions are needed. (C) 2010 Elsevier Ltd. All rights reserved.”
“An amylase with a molecular mass of 55 kDa and an N-terminal

sequence exhibiting similarity to enzyme from Bacteroides thetaitaomicron was isolated from fruiting bodies of the monkey head mushroom Hericium erinaceum. The purification scheme included extraction with distilled water, ion exchange chromatography on DEAE-cellulose and SP-sepharose, and gel filtration by FPLC on Superdex 75. The amylase of H. erinaceum was adsorbed on DEAE-cellulose in 10 mM Tris-HCl buffer (pH 7.4) and eluted with 0.2 M NaCl in the same buffer. The enzyme was subsequently adsorbed on SP-Sepharose in selleck 10 mM ammonium acetate buffer (pH 4.5) and eluted with 0.3 Sonidegib chemical structure M NaCl in the same buffer. This fraction was subsequently subjected to gel filtration on Superdex 75. The first peak eluted had a molecular mass of 55 kDa in SDS-PAGE. The amylase of H. erinaceum exhibited a pH optimum of 4.6 and a temperature optimum of 40A degrees C. The enzyme activity was enhanced by Mn2+ and Fe3+ ions, but inhibited by Hg2+ ions.”
“Purpose of the research:

Oral cancer is a common malignant disease in Taiwan. The purpose of this prospective follow-up study was to identify the changes in quality of life for newly diagnosed oral cancer patients during the acute stage.

Methods and sample: Subjects were recruited from the outpatient department (OPD) in a medical center located in the northern part of Taiwan. 22 subjects completed both the EORTC QLQ-C30 and the EORTC QLQ-H&N35 at diagnosis, postoperative discharge, and the first postoperative follow-up. In addition, 91% of the subjects received surgery only as their main treatment.

Key results: During the three assessments, as measured by the EORTC QLQ-C30, subjects reported that their physical function was much better at diagnosis than at both postoperative discharge and first postoperative follow-up. Their role functioning was much better at diagnosis than at postoperative discharge. Nevertheless, subjects reported better emotional functioning at the first postoperative follow-up than at the other two points of assessment.

The etiology includes genetic and environmental factors. Diagnosis is based on the typical erythematous, scaly skin lesions, often with additional manifestations in the nails and joints. Plaque psoriasis is the most common form. Atypical forms include guttate, pustular, erythrodermic, and

inverse psoriasis. Psoriasis is associated with several comorbidities, including cardiovascular disease, lymphoma, and depression. Topical therapies such as corticosteroids, vitamin D analogs, and tazarotene are useful for treating mild to moderate psoriasis. More severe psoriasis may be treated with phototherapy, or may require systemic click here therapy. Biologic therapies, including tumor necrosis factor inhibitors, can be effective for severe psoriasis and psoriatic arthritis, but have significant adverse effect profiles and require regular monitoring. Management of psoriasis must be individualized and may involve combinations of different medications and phototherapy.

“Objective: To compare the renoprotective effects of the calcium channel blocker (CCB) benidipine (CAS 105979-17-7) and the angiotensin 11 receptor blocker (ARB) valsartan (CAS 137862-53-4) in primary hypertensive patients with GSK1120212 inhibitor proteinuria.

Methods: 236 patients with primary hypertension were randomly divided into DAPT in vivo different groups and were administered either benidipine or valsartan. The alterations of the glomerular filtration rate (GFR) and proteinuria were compared between the different groups.

Results: Valsartan could decrease the level of proteinuria significantly as compared with that in benidipine-treated hypertensive patients with proteinuria at levels < 1 g/24 h (P < 0.01). There was no significant difference of the effects of benidipine and valsartan oil proteinuria reduction in hypertensive patients with proteinuria at levels 1-3 g/24 h. There was no significant difference of the effects of benidipine and valsartan on GFR in benidipine- and valsartan-treated patients.

Conclusion:

The results showed that valsartan was more effective in decreasing the levels of proteinuria in hypertensive patients with proteinuria at an early stage of nephropathy. The renoprotective effects of benidipine and valsartan in primary hypertensive patients with proteinuria were similar.”
“AMP-activated protein kinase (AMPK) is one of the major energy sensor at both: cellular and whole body level. It exists as heterotrimer containing three subunits: the catalytic alpha subunit, beta and regulatory gamma. AMPK is localized both in the cytoplasm and in the nucleus. It is activated by increasing concentrations of AMP during the energy shortage, causing activation of catabolic pathways and inhibition of energy consuming processes.

After regeneration for seven days, DjStag was weakly expressed. A similar decrease occurs regardless of the orientation of the cut. The expression pattern did not differ significantly in the different types of regeneration. Relative quantitative real-time PCR analysis of DjStag mRNA indicated that the expression of DjStag mRNA was increased after amputation compared to that in normal intact planarians, and the maximum level Nutlin-3 of expression of DjStag transcripts occurred

at five days after amputation. All results suggest that DjStag, implicated in planarian regeneration, plays a role in maintaining the ability of pluripotent stem cells to regenerate lost tissue in planarians.”
“Objectives: Cytochrome P450 (CYP) 2C19 is expressed in vascular endothelium and metabolizes arachidonic acid to biologically active epoxyeicosatrienoic acids (EETs), which are potent endogenous vasodilators and inhibitors of vascular inflammation. The purpose of this study is to explore the relationship between the interaction of CYP2C19*3 polymorphism

and smoking and coronary artery disease (CAD) in a Uighur population. Methods: In a Chinese Uighur case-control study of patients with CAD (n = 336) and healthy controls (n = 370), we investigated the roles of polymorphism in the CYP2C19 gene by the use of polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analysis. Results: The CYP2C19*3 AG broken vertical bar AA genotype was

significantly more prevalent in patients with CAD (6.25.0% click here vs 2.96%; P = .03). Multiple logistic regression analysis showed 4 independent risk factors: the interaction of CYP2C19*3 and smoking (OR 7.22, 95% confidence interval [CI] 2.32-10.23; P = .009), smoking (OR 3.23, 95% CI 1.72-5.44; P = .003), blood sugar (OR 2.12, 95% CI 1.03-4.21; P < .01), and hypertension (OR 1.74, https://www.selleckchem.com/products/sn-38.html 95% CI 0.98- 2.34; P = .013). Conclusions: The CYP2C19*3 polymorphism and CAD were synergistically and significantly associated in Chinese Uighur patients.”
“This study of aerodynamic mass-weighted particle size distribution (APSD) data from orally inhaled products (OIPs) investigated whether a set of simpler (than currently used) metrics may be adequate to detect changes in APSD for quality control (QC) purposes. A range of OIPs was examined, and correlations between mass median aerodynamic diameter and the ratio of large particle mass (LPM) to small particle mass (SPM) were calculated. For an Andersen cascade impactor, the LPM combines the mass associated with particle sizes from impactor stage 1 to a product-specific boundary size; SPM combines the mass of particles from that boundary through to terminal filter. The LPM-SPM boundary should be chosen during development based on the full-resolution impactor results so as to maximize the sensitivity of the LPM/SPM ratio to meaningful changes in quality.

RESULTS: In the study, 121 TB patients and 371 controls participated. The mean age was 30 years: 56.3% were male and 43.7% female. Of the TB patients, 87% had malnutrition compared to 33%, among controls. The

mean body mass index (BMI) click here of the patients was significantly lower than that of the controls (16.1 +/- 2.3 kg/m(2) VS. 19.4 +/- 3.0 kg/m(2)). Factors associated with the development of TB were BMI (OR 0.5, 95%CI 0.40.6), family history of TB (OR 3.2, 95 %CI 1.6-6.4), living In an extended family (OR 2.7, 95%CI 1.5-4.8), being non-indigenous to Timor and Rote Islands (OR 2.9, 95%CI 1.2-6.8) and being unemployed (OR 3.8, 95%CI 1.7-8.6).

CONCLUSION: Among patients with active pulmonary TB, the prevalence of malnutrition was very high. Malnutrition, which is a general problem for the whole community and particularly among people not indigenous to Timor and Rote, should be addressed in the fight against TB.”
“Background and Purpose: A baseline kidneys, ureters, and bladder (KUB) radiograph, at the time of computed tomography (CT) for ureteral

stones, might aid interpretation of future KUBs. The CT scout radiograph might render the baseline KUB redundant, however. We sought to assess the diagnostic utility of baseline KUB for patients with ureteral stones. Patients and Methods: Patients with ureteral stones were retrospectively identified. All had a baseline KUB in addition to CT and were reassessed after 4 to 60 days with KUB. Each patient’s imaging was randomized 1:1 into either KUB&CT or CT groups. Three VX-770 cost urologists independently assessed the imaging: CT (with scout film) and baseline KUB in the KUB&CT group, but only the CT (not KUB) in the CT group. Definitive stone assessment on follow-up KUB was defined as all three reviewers answering either Yes or No (not Indeterminate) to the question of stone passage or migration. Results: Of 154 stones, the mean diameter was 4.82.1mm, density was 914 +/- 300 Hounsfield units (HU), with 54.4% in the distal AZD5582 in vivo ureter.

Stone visibility was 60.4% on KUB vs 43.5% on scout film (P<0.001). Scout film visibility favored the CT group (52.7 vs 35.0%, P=0.027). After adjusting for body mass index, skin-to-stone distance, size, density, and location, definitive assessment rates were higher in the KUB&CT group (P=0.047). When reviewers reassessed the CT group using the baseline KUB, they were able to do so definitively in an additional 16 (21.6%, P<0.001). Definitive assessments were associated with higher rates of stone visibility on scout film (86.1 vs 21.1%, P<0.001), KUB (86.1 vs 50.0%, P<0.001), and larger (6.0 vs 3.7mm, P<0.001), denser stones (1046 vs 802 HU, P<0.001). Conclusions: The addition of a baseline KUB to the CT scout film improves the ability of urologists to determine stone outcome when following patients with KUB imaging and might reduce the subsequent need for additional imaging.

Acute effects of OA on kidney function and mean arterial blood pressure ( MAP) were investigated in anesthetized rats challenged with hypotonic saline after a 3.5-h equilibration

for 4h of 1 h control, 1.5 h treatment, and 1.5 h recovery periods. OA was added to the infusate during the treatment period. Chronic effects of OA were studied in individually caged rats treated twice daily with OA (60 mg/kg, p.o.) for five weeks. By comparison with respective control animals administration, OA significantly increased PFTα mouse Na(+) excretion rates of non-diabetic and STZ-induced diabetic rats without affecting urine flow, K(+) and Cl rates. At the end of five weeks, OA treatment significantly (p < 0.05) increased Ccr in non-diabetic (2.88 +/- 0.14 vs. 3.71 +/- 0.30 ml/min) and STZ-diabetic rats (1.81 +/- 0.32 vs. 3.07 +/- 0.16 ml/min) with concomitant reduction of plasma creatinine concentration (n = 6 in all groups). OA also caused significant decreases in MAP in nondiabetic and STZ-induced diabetic rats. These findings suggest that OA may have beneficial effects on some processes associated with renal derangement of STZ-induced diabetic rats.”
“Bone marrow mesenchymal stem (stromal) cells (MSCs) are shown to differentiate into different renal lineages in in vivo injury models. Nevertheless, the in vitro differentiation

of MSCs into a renal tubular epithelial lineage has not been investigated. We hypothesize that the injured renal epithelial cells express renotypic factors that may influence the differentiation of MSCs into a renal tubular epithelial lineage. MSCs were cocultured for up to this website seven days with injured or uninjured murine cortical tubular renal epithelial cells (MCTs), which are separated by a physical barrier; following the coculture, MSCs were examined for the expression of two renal tubular epithelial-specific markers,

kidney-specific cadherin (Ksp-cadherin) and aquaporin-1 (AQP1). MSCs differentiated into a tubular epithelial-like phenotype, as shown by the appearance of Ksp-cadherin and AQP1 by day 7 when cocultured with injured MCTs. Further, MSCs showed tubulogenic characteristics when cocultured in a three-dimensional matrix. Nonetheless, MSCs cultured with the conditioned medium from injured find more MCTs, cocultured with ureteric bud cells, or treated with nephrogenic factors did not differentiate into renal epithelial cells. Based on our findings, we conclude that MSCs can differentiate into a renal epithelial lineage independent of cell fusion when cocultured with injured renal cells.”
“Puccinia striiformis f. sp. tritici (Pst) causes stripe rust, one of the most important diseases of wheat worldwide. cDNA libraries had been constructed from urediniospores, germinated urediniospores and haustoria. However, little is known about the expression patterns of the genes related to the infection process and sporulation of the pathogen.

Compound 1 showed significant anti-tumour activity.”
“Objective: To evaluate a two-step screening protocol of ultrasound examinations (11-14 and 20-24 weeks) for the detection of major fetal structural defects. Methods: Retrospective study in a private maternity hospital. Women with viable singleton pregnancies having both first trimester scan and anomaly scan at our department and subsequently delivered at our hospital were included. Major fetal structural defects were defined as those requiring medical or surgical treatment or those causing mental

handicap. Results: A total of 3,902 pregnancies included 61 fetuses with structural defects (1.56%). Twenty-six (42.6%) were diagnosed in the first trimester and 29 (47.5%) in the second. BTSA1 research buy Six anomalies were detected in the third trimester or after birth. Overall detection rate of the two-step program was 90.2%. Conclusions: Detailed examination of fetal anatomy R788 inhibitor at 11-14 weeks resulted in the

early diagnosis of about 40% of major structural defects”
“Background To improve the therapeutic effects of gastric electrical stimulation (GES) for obesity, an animal experiment was conducted using a new type of stimulators. Proper parameters of GES were selected, and the impacts of GES on the food intake and gastric accommodation of canines were observed.

Methods Eight beagle dogs were operated on, and GES was performed on them. Firstly, GES was performed to determine the right parameters according to symptoms. Secondly, the so selected parameters were used in a 3-day GES procedure, during which process food intake, body weight, and symptoms were recorded. Thirdly, the gastric capacities before and after GES with different pulse widths were measured by means of a barostat.

Results The selected parameters varied for each dog, with the pulse widths ranging from 0.3 to 6

ms. The food consumption after GES dropped P505-15 chemical structure significantly as compared with the amount observed in the sham stimulation. Tolerance to stimulation could be observed during GES. The post-GES gastric fundus capacity increased evidently in comparison with the capacity before GES, suggesting significant distention as compared with sham stimulation. Given an increment of 2 ms in the pulse width twice, the gastric capacity continued to distend each time.

Conclusions GES featuring pulse trains with wider and individualized pulse widths could inhibit food consumption of dogs. The stimulation parameters should be selected individually and adjusted periodically. GES of this mode could also increase the fasting gastric capacity with certain dose-related effects. The new type of stimulators may be more suitable for the treatment of human obesity than traditional stimulators.

Acute rejection occurring during the first 3 months after transplantation was more frequent in the ATG group (52.4% vs. 25%). Moreover, late acute rejection episodes occurred in all Fer-1 purchase recipients in whom weaning was attempted and no recipients reached the primary end-point. This motivated the premature termination of the trial. Tacrolimus trough levels were lower in the ATG-Fresenius group but no benefits in terms of improved renal function, lower metabolic complications or increased prevalence of tolerance-related biomarkers were observed. In

conclusion, the use of ATG-Fresenius and tacrolimus at gradually decreasing doses was associated with a high rate of rejection, did not allow for the administration of very low doses of tacrolimus and failed to provide detectable clinical benefits. ClinicalTrials.gov identifier:NCT00436722.”
“Homogeneous distribution of magnetic dopants in semiconductor hosts is highly desired for practical applications in spintronics.

Herein, we show that codoping 2 at. % Cu with Zn0.98Co0.020 could change the magnetic behavior from paramagnetism to room temperature ferromagnetism. For Zn0.96Cu0.02Co0.02O nanocrystals prepared by a modified solid-state reaction method, the combination of x-ray absorption fine structure spectra at Co, Cu, and O K-edge reveals that the Cu and Co ions are substitutionally incorporated into the ZnO matrix and distribute randomly in the host. First-principles calculations further indicate strong hybridization between Co 3d states and Cu-induced donor impurity bands at the Fermi level, which effectively S63845 supplier enhances the indirect ferromagnetic superexchange of Co ions and is responsible for the occurrence of ferromagnetism in (Co,Cu)-codoped ZnO.

“Any use of alcohol in the years following liver transplantation (LTX)

approaches 50% of patients transplanted for alcoholic liver disease (ALD). We collected detailed prospective data on alcohol consumption following LTX for ALD to investigate ongoing patterns of use. Using trajectory modeling selleck chemicals we identified four distinct alcohol use trajectories. One group had minimal use over time. Two other groups developed early onset moderate-to-heavy consumption and one group developed late onset moderate use. These trajectories demonstrate that alcohol use varies based on timing of onset, quantity and duration. Using discriminant function analysis, we examine characteristics of recipient’s pre-LTX alcohol histories and early post-LTX psychological stressors to identify the profile of those at risk for these specific trajectories. We discuss the relevance of these findings to clinical care and preliminarily to outcomes.”
“Molecular dynamics simulations were performed to evaluate temperature-dependent thermal conductivity of bent carbon nanotubes.

Results: Many adipose carotenoids were inversely related to percentage body fat, although lycopene was the only carotenoid inversely correlated with all 3 sites. Most of the carotenoids were significantly higher in the abdominal adipose tissue than in the thigh (P < 0.05). Concentrations of alpha-carotene, beta-carotene, 5-cis-lycopene, and total carotenoids were significantly higher in the buttocks than in the thigh (P < 0.05). Concentrations

of alpha-carotene, cis-lycopene, and lutein (with or without zeaxanthin) were significantly higher in the abdomen than in the buttocks (P < 0.05). Dietary intake was significantly correlated with serum concentrations of alpha-carotene, beta-carotene, beta-cryptoxanthin, and total carotenoids. Carotenoid intake was significantly

correlated with adipose tissue concentrations of alpha-carotene, beta-carotene, beta-cryptoxanthin, cis-lycopene, and ATM inhibitor total carotenoids (P < 0.05) but varied by site. Of all the adipose tissue sites evaluated, the abdomen showed the strongest correlation with long-term dietary carotenoid intakes and with serum (indicator of short-term intake) for most carotenoids.

Conclusions: Body fat may influence the tissue distribution of carotenoids. Abdominal adipose tissue carotenoid concentrations may be a useful Metabolism inhibitor indicator of carotenoid status. Am J Clin Nutr 2009;90:533-9.”
“High performance polymer, Polyether Ether Ketone (PEEK) (service temperature -250 degrees C to +300 degrees C, tensile strength: 120 MPa) is gaining significant interest in aerospace and automotive industries.

In this investigation, attention is given to understand adhesion properties of PEEK, see more when surface of the PEEK is modified by two different plasma processes (i) atmospheric pressure plasma and (ii) low pressure plasma under DC Glow Discharge. The PEEK sheets are fabricated by ultra high temperature resistant epoxy adhesive (DURALCO 4703, service temperature -260 degrees C to +350 degrees C). The surface of the PEEK is modified through atmospheric pressure plasma with 30 and 60 s of exposure and low pressure plasma with 30, 60, 120, 240, and 480 s of exposure. It is observed that polar component of surface energy leading to total surface energy of the polymer increases significantly when exposed to atmospheric pressure plasma. In the case of low pressure plasma, polar component of surface energy leading to total surface energy of the polymer increases with time of exposure up to 120 s and thereafter, it deteriorates with increasing time of exposure. The fractured surface of the adhesively bonded PEEK is examined under SEM. It is observed that unmodified PEEK fails essentially from the adhesive to PEEK interface resulting in low adhesive bond strength.

Then, 2 g cyclophosphamide was injected every 2 days, but no remarkable improvement was observed. Nine months later his inhibitor titers were high. The inhibitor and factor VIII concentrations were assessed I I times during these 13 months, and the mean level of factor VIII inhibitor was 44 BU (with a minimum of 2 BU and a maximum of 103 BU); the minimum and maximum factor VIII concentrations were <1% and 20%, respectively. The patient experienced hemarthroses,

severe epistaxis, hematoma, and gastrointestinal bleeding episodes during this phase. His factor VIII concentration spontaneously and gradually improved Selleckchem GSK2118436 and increased to 51.5% 8 months after stopping the treatment with undetectable factor VIII inhibitor.”
“Although the terpenoid pathway constitutes, with the phenylpropanoid metabolism, the major pathway of secondary metabolism in plants, little is known about its regulation. Overexpression of a Vitis vinifera R2R3-MYB transcription factor (VvMYB5b) in tomato induced pleiotropic changes including dwarfism, modified leaf structure, alterations of floral morphology, pigmented and glossy fruits at the “”green-mature”" Protein Tyrosine Kinase inhibitor stage and impaired seed germination. Two main branches of secondary metabolism, which

profoundly influence the organoleptic properties of the fruit, were affected in

the opposite way by VvMYB5b overexpression. Phenylpropanoid metabolism was down regulated whereas the amount of beta-carotene was up regulated. This is the first example of the independent regulation of phenylpropanoid and carotenoid metabolism. The strongest Selleck BI 2536 modification concerns a decrease in beta-amyrin, the precursor of the oleanolic acid, which is the major component of grape waxes. Scanning electron microscopy analysis of fruits and leaves confirms the alteration of wax metabolism and a modification of cell size and shape. This may potentially impact resistance/tolerance to biotic and abiotic stresses. The results are compared with a similar approach using heterologous expression of VvMYB5b in tobacco.

“A case of an 18-year-old man with deep venous thrombosis of the lower limbs caused by hypoplasia of the inferior vena cava in combination with heterozygous factor V Leiden is presented. Both anomalies were found when the patient complained of venous claudication in both thighs. Inferior vena cava malformation is a rare condition and may predispose to the development of deep venous thrombosis. This patient was at an even higher risk for deep venous thrombosis as the inferior vena cava malformation was combined with a hypercoagulable state.

Methods: Four hundred and sixty-three patients with symptomatic single-level lumbosacral degenerative disease with no greater than grade-1 spondylolisthesis were

treated with single-level instrumented posterolateral arthrodesis through an open midline approach. Patients were randomly assigned to either the recombinant human bone morphogenetic protein-2 matrix group (239 patients) or the autogenous iliac crest bone-graft selleck compound group (224 patients). The Oswestry Disability Index, Short Form-36, and back and leg pain scores were determined preoperatively and at 1.5, three, six, twelve, and twenty-four months postoperatively. Radiographs and computed tomography scans were made at six, twelve, and twenty-four months postoperatively to evaluate for fusion.

Results: The mean operative time and mean

blood loss in the recombinant human bone morphogenetic protein-2 matrix group (2.5 hours and 343.1 mL, respectively) were significantly less than those in the iliac crest bone-graft group selleck kinase inhibitor (2.9 hours and 448.6 mL). Both groups showed similar improvements in clinical outcomes and reduced pain. At twenty-four months, 60% of the iliac crest bone-graft group reported donor-site pain. At twenty-four months, fusion was evident in 96% of the patients in the recombinant human bone morphogenetic protein-2 matrix group compared with 89% in the iliac crest bone-graft group (p = 0.014). There was a significant difference (p = 0.011) in the rate of failures because of nonunion (eighteen patients with an iliac crest bone graft compared with six patients with the recombinant human bone morphogenetic protein-2 matrix). Also, the number of patients requiring second surgeries was significantly higher in the iliac GSK3235025 mouse crest bone-graft group (thirty-six patients) compared with

the recombinant human bone morphogenetic protein-2 matrix group (twenty patients) (p = 0.015).

Conclusions: The use of recombinant human bone morphogenetic protein-2 in instrumented posterolateral lumbar arthrodesis decreases operative time and blood loss and produces earlier and higher fusion rates than does iliac crest bone graft. Clinical outcomes are similar to those with iliac crest bone graft. Thus, the need for harvesting iliac crest bone is eliminated along with the morbidities associated with the harvest procedure.”
“Purpose of review

This review evaluates recently published literature examining various muscle tissue cells and their modulators that determine whether injured skeletal muscle will fully regenerate or become fibrotic.

Recent findings

Muscle regeneration is a complex process involving several interacting cell types. Macrophages initiate a cytokine response to injury that both directs the subsequent inflammatory response and promotes nonmyeloid proliferation. Muscle cells and their progenitors produce autocrine and paracrine growth factors that help inhibit or stimulate muscle growth and regeneration.
