RESUMO
PURPOSE: The aim of the present study was to assess the effect of Bacillus coagulans Unique IS-2 supplementation on absorption and utilization of protein in resistance-trained males. METHODS: In this double blind, placebo-control trial, resistance-trained males (21.08 ± 2.84 years) were randomized to consume, either 20 g of whey protein powder {80% whey protein concentrate (WPC80), amounting to 15.4 g protein} with 2 billion CFU Bacillus coagulans Unique IS-2 (supplemental group) or 20 g of whey protein powder and lactose instead of Bacillus coagulans (placebo group) once daily for 60 days with a controlled resistance exercise protocol. The whey protein concentrate (WPC-80) given to both groups had a lactose content of 6.8%. Plasma-free amino acids (PFAAs) were determined at baseline, at 30 and 60 days of supplementation. Muscle strength, hypertrophy, VO2 max, and body composition, and other biochemical parameters were assessed at baseline and end line. RESULTS: A positive effect of probiotic Bacillus coagulans Unique IS-2 supplementation was observed on protein absorption as evidenced by an increase in total PFAA by + 16.1% (p = 0.004). Branched chain amino acids (BCAA) comprising isoleucine (p = 0.016), leucine (p = 0.001), and valine (p = 0.002) were increased by + 33.1% in ITT analysis as compared to placebo after 60 days. At 30 days an increase in isoleucine by + 35% (p = 0.113), leucine by + 43% (p = 0.032), and valine by + 32% (p = 0.017) was observed in ITT analysis. Probiotic effect was shown on exercise performance as evidenced by an increase in one RM of leg press and vertical jump power by + 16.61% (p = 0.024) and + 7.86% (p = 0.007), respectively. CONCLUSION: Significantly increased absorption of BCAA with supplementation of B. coagulans Unique IS-2 along with whey protein and improvement in leg press and vertical jump power was noted indicating the positive effect of the probiotic on muscle power in the lower body.

BACKGROUND: Alzheimer's disease (AD) is the progressive brain disorder which degenerates brain cells connection and causes memory loss. Although AD is irreversible, it is not impossible to arrest or slow down the progression of the disease. However, this would only be possible if the disease is diagnosed at an early stage, and early diagnosis requires clear understanding of the pathogenesis at molecular level. Overactivity of GSK-3ß and p53 accounts for tau hyperphosphorylation and the formation of amyloid-ß plaques. OBJECTIVE: Here, we explored GSK-3ß and p53 as blood-based biomarkers for early detection of AD. METHODS: The levels of GSK-3ß, p53, and their phosphorylated states were measured using surface plasmon resonance and verified using western blot in serum from AD, mild cognitive impairment (MCI), and geriatric-control (GC) subjects. The neurotoxic SH-SY5Y cell line was treated with antioxidant Emblica Officinalis (EO) for rescue effect. RESULTS: GSK-3ß, p53, and their phosphorylated states were significantly over expressed (pâ>â0.001) in AD and MCI compared to GC and can differentiate AD and MCI from GC. The expression level of GSK-3ß and p53 proteins were found to be downregulated in a dose-dependent manner after the treatment with EO in amyloid-b-induced neurotoxic cells. CONCLUSION: These proteins can serve as potential blood markers for the diagnosis of AD and EO can suppress their level. This work has translational value and clinical utility in the future.

The present study explores the efficacy of 12-week yoga + diet-based lifestyle intervention (YBLI) vs dietary intervention (DI) on health-related quality of life (HRQoL) and identifies the predictors of change in HRQoL in Indians with metabolic syndrome (Met S). Data from the historical randomized controlled trial was used including adults (n = 260, 20-45 years) with Met S. Four domains of HRQoL were measured at baseline, 2 and 12 weeks using WHOQOL-BREF questionnaire. Generalized estimating equation and chi-square test was used to compare 12-week changes in HRQoL domains and proportion of subjects, respectively. Changes in HRQoL were predicted using regression models concerning changes in body mass index (BMI), physical activity, total calorie intake, adiponectin, and superoxide dismutase (SOD) levels. Exploratory mediation analysis was carried out using Baron & Kenny approach. YBLI resulted in a significantly greater increase in the physical domain score of HRQoL than DI. A significantly greater proportion of subjects in YBLI group (71%) showed an increase in physical domain scores compared to DI (51%). A unit change in BMI negatively predicted a unit change in physical, psychological and environmental health. Whereas, a unit change in adiponectin and SOD levels positively predicted a unit change in physical and environmental health. Partial mediation between YBLI intervention and physical HRQoL domain was observed via adiponectin. In conclusion, a 12-week YBLI has a positive and greater effect on HRQoL physical domain score than following DI alone. Changes in BMI, adiponectin, and SOD levels may predict changes in HRQoL domains after lifestyle intervention.

RESUMO
Vitamin D deficiency may contribute to etiology of type 2 diabetes in Asian Indians. The objectives of this study was to evaluate effect of vitamin D supplementation on glycemic profile and body composition in prediabetic and vitamin D deficient overweight/obese Asian Indian women. In this open-label randomized placebo-controlled trial (78 weeks duration), 121 females (aged 20-60 years) with prediabetes and vitamin D deficiency were randomly allocated in intervention (n, 61) and placebo (n, 60) groups. The primary outcome variables were fasting blood glucose (FBG), 2-h blood glucose post OGTT (2-h BG), hemoglobin A1c (HbA1C), and reversal to normoglycemia. In Intention-to-treat analysis, at the end of intervention, we observed significant decrease in FBG [-5.0 (-12.6-2.4), p = 0.04], 2-h blood glucose post OGTT [-11(-49.3-26.9), p = 0.02], hemoglobin A1c [-0.41 (5.89, 6.55), p = 0.05] and increase in 25(OH) D [7.5 (-6.0-20.9), p = 0.002] levels in intervention as compared to the placebo group. Changes in glycemic category based on FBG were as follows; intervention group: normal FBG, 58.6%; impaired fasting glucose (IFG), 39%; and type 2 diabetes mellitus (T2DM), 2.4%; placebo group: normal FBG, 48.8%; IFG, 46.3%; and T2DM, 4.9%. Changes in category of 2-hour glucose post OGTT after intervention were as follows; intervention group: normal glucose tolerance (NGT) 51.2% and prediabetes, 48.8%; placebo group: NGT, 43.9%; prediabetes, 53.7% and T2DM, 2.4%. After intervention, subscapular skinfold (visit Ist compared to visit IIIrd) and suprailiac skinfold (visit IInd compared to visit IIIrd) were significantly lower in intervention group vs. control group. In conclusion, we observed significant reduction in FBG, 2-hour glucose post OGTT, HbA1c, and truncal subcutaneous fat and reversal to normoglycemia in overweight/obese prediabetic vitamin D deficient Asian Indian women after 78 weeks of vitamin D supplementation.

Metabolic syndrome, a prediabetic and precardiovascular pathologic condition that begins early in life, tracks into adulthood and magnifies with age. Randomized controlled trials evaluating efficacy of yoga-based lifestyle vs. dietary intervention on metabolic syndrome are lacking. Here, the efficacy of a 12-week yoga-based lifestyle intervention vs. dietary intervention on cardio-metabolic risk factors and metabolic syndrome risk scores have been assessed in Indian adults with metabolic syndrome. In this two-arm, open label, parallel group, randomized controlled trial, 260 adults (20-45 years) diagnosed with metabolic syndrome as per joint interim statement, 2009 were randomized to yoga-based (including diet) lifestyle or dietary intervention alone (n = 130, each) for 12 weeks. Primary endpoints were the 12-week changes in cardio-metabolic risk factors and metabolic risk scores. The secondary endpoints were the 12-week changes in the proportion of subjects recovered from metabolic syndrome, dietary intake, and physical activity. Intent-to-treat analysis was performed including all the subjects with baseline data with imputed missing data. Treatment × time interaction showed yoga-based lifestyle intervention had a greater treatment effect over dietary intervention by significantly reducing waist circumference, continuous metabolic syndrome z-score, and dietary intake/day while significantly increasing physical activity. High-density lipoprotein cholesterol showed a significantly greater reduction following dietary intervention than yoga-based lifestyle intervention. A significantly greater proportion of subjects recovered from metabolic syndrome in yoga-based lifestyle (45.4%) vs. dietary intervention group (32.3%). A 12-week yoga-based lifestyle intervention is more efficacious than usual dietary intervention in improving cardio-metabolic risk factor and metabolic risk score in Indian adults with metabolic syndrome.

Sestrin2 (Sesn2) appears to mediate neuroprotection against Parkinson's disease (PD)-associated pathophysiology, however, the mechanism is unknown. This pilot study examines serum Sesn2 level in PD patients and older adult control and also interrogates the rescue effect of Syzygium aromaticum extract on the neurotoxicity by paraquat in neuroblastoma cells. The blood sample was collected from 36 PD patients and 54 older adult control and concentration of serum Sesn2 was measured by surface plasmon resonance and western blot. A significantly elevated level of Sesn2 (p < .0001) was observed in sera of PD group (15.96 ± 2.428 ng/µL) than the control (13.65 ± 2.125 ng/µL) which was further confirmed by western blotting. The receiver operating characteristic (ROC) curve (0.76) determined the threshold value of ≥14.58 ng/µL for differentiating PD from control. The S aromaticum extract exhibited the rescue effect from paraquat induced toxicity in SH-SY5Y cells. Further, these cells showed dose-dependent downregulation of p53, Sesn2, and phosphorylated-AMPK with concomitant increase in phosphorylated-p70S6K level than paraquat-treated cells. The differential level of Sesn2 in study subjects proposes its utility as one of the potential serum markers in PD. The ethanolic extract of S aromaticum may serve as a novel platform for management of PD-associated neurotoxicity.

The developing visual circuitry attains its mature adult pattern through the process of activity-dependent refinement in which photic stimulation plays the major role. However, auditory stimulation can also facilitate the developing visual Wulst synaptic plasticity and postnatal perceptual behavior, though the underlying mechanism is unclear. We exposed the fertilized eggs of white Leghorn chickens during incubation to either species-specific calls or no sound for varying time periods depending on the functional development of the auditory and/or visual systems. The visual evoked potential (VEP) from the Wulst was recorded at embryonic days (E) 19, 20 and posthatch days (PH) 1-3, to assess functional maturation. A significant attenuation in latencies and higher amplitudes at PH1-3 in the stimulated groups that received exposure during visual system maturation, suggest beneficial effect of auditory inputs only during critical periods. Concomitant with this, there was a significant increase in the expression of BDNF and levels of neurotransmitters GABA, glutamate, norepinephrine and serotonin from E18 only in both hemispheres of the visual Wulst. A significant inter-hemispheric difference in expression was also found in all groups. These results suggest the role of BDNF in activity driven structural and functional maturation of the visual system following prenatal repetitive auditory stimulation.

OBJECTIVE: The aim of this study is to evaluate the effect of oral glutamine (GL) supplementation on gut permeability and endotoxemia (surrogate end point) in patients with severe acute pancreatitis. METHODS: In a randomized controlled trial, patients were randomized to be given placebo or GL for 7 days. The primary outcome measures include the effect on gut permeability (assessed by lactulose/mannitol excretion in urine and endotoxemia assessed by endotoxin core antibodies type IgG and IgM (EndoCab IgG and IgM). The secondary outcome measures include infectious complications, mortality, total hospital/intensive care unit stay, C-reactive protein, and prealbumin levels. RESULTS: Patients were assigned to GL (n = 41) and placebo (n = 39) groups. There was no change in gut permeability after the intervention. However, the EndoCab IgM levels increased significantly (33 [4, 175] to 40 [8, 350] GMU/mL; P = 0.0164) and the C-reactive protein levels decreased significantly (133 [1, 287] to 88 [1, 267] ng/mL; P = 0.0236) in the GL group. No difference was observed in infectious complication, prealbumin value, hospital/intensive care unit stay, and mortality in both groups. CONCLUSIONS: No significant trend was identified for an effect of GL on gut permeability. Decreased inflammation and endotoxemia did not translate into reduced infectious complications in severe acute pancreatitis. However, the study was underpowered to detect the aforementioned difference (trial registration: CTRI/2009/000945).

Rhythmic sound or music is known to improve cognition in animals and humans. We wanted to evaluate the effects of prenatal repetitive music stimulation on the remodelling of the auditory cortex and visual Wulst in chicks. Fertilized eggs (0 day) of white leghorn chicken (Gallus domesticus) during incubation were exposed either to music or no sound from embryonic day 10 until hatching. Auditory and visual perceptual learning and synaptic plasticity, as evident by synaptophysin and PSD-95 expression, were done at posthatch days (PH) 1, 2 and 3. The number of responders was significantly higher in the music stimulated group as compared to controls at PH1 in both auditory and visual preference tests. The stimulated chicks took significantly lesser time to enter and spent more time in the maternal area in both preference tests. A significantly higher expression of synaptophysin and PSD-95 was observed in the stimulated group in comparison to control at PH1-3 both in the auditory cortex and visual Wulst. A significant inter-hemispheric and gender-based difference in expression was also found in all groups. These results suggest facilitation of postnatal perceptual behaviour and synaptic plasticity in both auditory and visual systems following prenatal stimulation with complex rhythmic music.

Objective. When exploring the scientific basis of reflexology techniques, elucidation of the surface and subsurface features of reflexology areas (RAs) is crucial. In this study, the subcutaneous features of RAs related to the lumbar vertebrae were evaluated by swept source-optical coherence tomography (SS-OCT) in subjects with and without low back pain (LBP). Methods. Volunteers without LBP (n = 6 (male : female = 1 : 1)) and subjects with LBP (n = 15 (male : female = 2 : 3)) were clinically examined in terms of skin colour (visual perception), localised tenderness (visual analogue scale) and structural as well as optical attributes as per SS-OCT. From each subject, 6 optical tomograms were recorded from equidistant transverse planes along the longitudinal axis of the RAs, and from each tomogram, 25 different spatial locations were considered for recording SS-OCT image attributes. The images were analysed with respect to the optical intensity distributions and thicknesses of different skin layers by using AxioVision Rel. 4.8.2 software. The SS-OCT images could be categorised into 4 pathological grades (i.e., 0, 1, 2, and 3) according to distinctness in the visible skin layers. Results. Three specific grades for abnormalities in SS-OCT images were identified considering gradual loss of distinctness and increase in luminosity of skin layers. Almost 90.05% subjects were of mixed type having predominance in certain grades. Conclusion. The skin SS-OCT system demonstrated a definite association of the surface features of healthy/unhealthy RAs with cutaneous features and the clinical status of the lumbar vertebrae.
RESUMO
OBJECTIVES: This study aimed to determine the effect of antioxidant (AO) supplementation on surrogate markers of fibrosis in patients with chronic pancreatitis (CP). METHODS: In a randomized, placebo (PL)-controlled trial, patients with CP were randomized to groups that were given PL or AO for 3 months. Outcome measures were change in serum levels of transforming growth factor ß1 and platelet-derived growth factor AA (PDGF-AA) (primary outcome) as well as blood markers of oxidative stress (thiobarbituric acid-reactive substances) and AO status (ferric-reducing ability of plasma) (secondary outcome). Pain relief and analgesic requirement was also recorded. RESULTS: Patients (n = 61; mean [SD] age, 35.2 [10.0]; male patients, 43) were assigned to AO (n = 31) and PL (n = 30) groups. The median (range) percent reduction from baseline to 3 months in levels of PDGF-AA (17.1% [-25.3% to 88.7%] vs 2.8% [-243.1% to 30.2%]; P = 0.001), transforming growth factor ß1 (P = 0.573), and thiobarbituric acid-reactive substances (P = 0.207) as well as percent increment from baseline to 3 months in ferric-reducing ability of plasma (P = 0.003) were higher in the AO group compared with the PL group. Proportion of patients who had both reduced PDGF-AA and reduced pain was greater in AO as compared with PL group (17/31 vs 9/30, P = 0.05) CONCLUSIONS: Reduction in markers of fibrosis (PDGF-AA) translated into clinical outcome (reduction in pain and analgesic requirements) in those supplemented with AOs in CP (trial registration, CTRI/2011/05/001747).
