First report on induced spawning of Siganus vermiculatus in India

Siganids are widely distributed to Indo-West Pacific region and the Siganus vermiculatus (Maze rabbit fish/Vermiculated spinefoot) can reach sizes that weigh up 2.3 kg each. It is a species of great aquaculture importance and hence breeding and seed production protocols are necessary. A major breakthrough in the seed production of Siganus vermiculatus by inducing the fishes to spawn under controlled conditions with Human Chorionic Gonadotropin (hCG) during the first quarter of the lunar cycle is reported. The hatchery processes and early larval stages are described

High-Resolution Sonography: A New Technique to Detect Nerve Damage in Leprosy

Mycobacterium leprae, which causes leprosy, infects peripheral nerves resulting in functional impairment, ulcer formation and stigmatizing deformities. Early diagnosis of nerve involvement is important to avoid nerve related complications. We used non-invasive, high-resolution sonography (US) and color Doppler (CD) imaging to study the ulnar (UN), median (MN), lateral popliteal (LP) and posterior tibial (PT) nerves in 20 leprosy patients and compared 30 healthy Indian controls. The nerves were significantly thicker in the patients (p<0.0001 for each nerve). One of the key signs of leprosy is the presence of enlarged nerves. The kappa for clinical palpation and nerve enlargement by sonography was 0.30 for all examined nerves. Increased neural vascularity, the sign of inflammation was observed in 26% (39/152) of nerves by CD imaging. Increased CD was observed in multiple nerves in 3 of 4 patients with type 2 reaction. Significant correlation was observed between clinical parameters of grade of thickening, sensory loss and muscle weakness and US abnormalities of nerve echotexture, endoneural flow and cross-sectional area (p<0.001). We conclude that sonography is a better diagnostic tool to predict nerve damage as compared to clinical assessment. Nerve damage was sonographically more extensive and was observed in nerves considered clinically normal

Impact of duration of stunting on compensatory growth and biometrics of snubnose pompano, Trachinotus blochii (Lacepede,1801) in low saline conditions

Compensatory growth (CG) pattern in snubnose pompano, Trachinotus blochii, stunted in low saline condition (< 15 ppt) was evaluated for its field level application. The fish were stunted for 30, 60 and 90 days by stocking 100 fish m− 3 providing a commercial feed (45% crude protein, 0.8 to 1.2 mm size) at sub-optimal level [3% of average body weight (ABW)]. Post-stunting rearing was carried out in triplicates for 30, 60 or 90 days at a stocking density of 20 fish m− 3 providing the same feed approximately 15% of ABW. Normal fish were maintained in triplicate at 20 fish m− 3 providing feed at optimum level (10% of ABW) throughout the experiment. Parameters such as weight gain pattern, final ABW and specific growth rate (%) per day (SGR/day) indicated near complete CG in 30 days stunted fish. A partial CG in 60 days stunted fish and no CG in 90 days stunted fish compared to corresponding normal fish was observed. The 60 days stunted fish was found ideal for field adoption with longer stunting period with better CG and survival. A field trial was conducted in circular cage by stunting the fish at 40 fish m− 3 (ABW = 5.4 g) feeding at 3% of ABW for 60 days. During post stunting, the stunted fish (10 fish m− 3) were reared in two cages feeding approximately 15% of ABW for 190 days. Parallely, normal fish (10 fish m− 3) were reared by feeding at 10% of ABW for 250 days. During stunting phase, the experimental fish exhibited a retarded growth (ABW = 18.9 g; SGR/day = 2.1) compared to normal (ABW = 27.9 ± 0.5 g; SGR/day = 2.7). In contrast, in post stunting phase, stunted fish exhibited partial CG (ABW = 116.23 ± 2.1 g; SGR/day = 0.71) compared to normal (ABW = 139.5 ± 15. 7 g; SGR/day = 0.8) with similar production (28.9 ± 1.8 g for stunted and 30.36 ± 4.3 g for normal) and higher survival (88.7%) than normal (77.5%). Biometric characteristics such as length - weight relationship (b value near 3) and condition factor (above 1) indicate natural growth in both stunted and normal fish. But size variation was higher in normal fish than stunted fish. Over all the experiments suggests that 60 days stunting in low saline conditions is ideal for ensuring good quality seed for farming of snubnose pompano

Yoga-Based Cardiac Rehabilitation After Acute Myocardial Infarction: A Randomized Trial

Background: Given the shortage of cardiac rehabilitation (CR) programs in India and poor uptake worldwide, there is an urgent need to find alternative models of CR that are inexpensive and may offer choice to subgroups with poor uptake (e.g., women and elderly). Objectives: This study sought to evaluate the effects of yoga-based CR (Yoga-CaRe) on major cardiovascular events and self-rated health in a multicenter randomized controlled trial. Methods: The trial was conducted in 24 medical centers across India. This study recruited 3,959 patients with acute myocardial infarction with a median and minimum follow-up of 22 and 6 months. Patients were individually randomized to receive either a Yoga-CaRe program (n = 1,970) or enhanced standard care involving educational advice (n = 1,989). The co-primary outcomes were: 1) first occurrence of major adverse cardiovascular events (MACE) (composite of all-cause mortality, myocardial infarction, stroke, or emergency cardiovascular hospitalization); and 2) self-rated health on the European Quality of Life–5 Dimensions–5 Level visual analogue scale at 12 weeks. Results: MACE occurred in 131 (6.7%) patients in the Yoga-CaRe group and 146 (7.4%) patients in the enhanced standard care group (hazard ratio with Yoga-CaRe: 0.90; 95% confidence interval [CI]: 0.71 to 1.15; p = 0.41). Self-rated health was 77 in Yoga-CaRe and 75.7 in the enhanced standard care group (baseline-adjusted mean difference in favor of Yoga-CaRe: 1.5; 95% CI: 0.5 to 2.5; p = 0.002). The Yoga-CaRe group had greater return to pre-infarct activities, but there was no difference in tobacco cessation or medication adherence between the treatment groups (secondary outcomes). Conclusions: Yoga-CaRe improved self-rated health and return to pre-infarct activities after acute myocardial infarction, but the trial lacked statistical power to show a difference in MACE. Yoga-CaRe may be an option when conventional CR is unavailable or unacceptable to individuals.

SPARC Overexpression Inhibits Cell Proliferation in Neuroblastoma and Is Partly Mediated by Tumor Suppressor Protein PTEN and AKT

Secreted protein acidic and rich in cysteine (SPARC) is also known as BM-40 or Osteonectin, a multi-functional protein modulating cell–cell and cell–matrix interactions. In cancer, SPARC is not only linked with a highly aggressive phenotype, but it also acts as a tumor suppressor. In the present study, we sought to characterize the function of SPARC and its role in sensitizing neuroblastoma cells to radio-therapy. SPARC overexpression in neuroblastoma cells inhibited cell proliferation in vitro. Additionally, SPARC overexpression significantly suppressed the activity of AKT and this suppression was accompanied by an increase in the tumor suppressor protein PTEN both in vitro and in vivo. Restoration of neuroblastoma cell radio-sensitivity was achieved by overexpression of SPARC in neuroblastoma cells in vitro and in vivo. To confirm the role of the AKT in proliferation inhibited by SPARC overexpression, we transfected neuroblastoma cells with a plasmid vector carrying myr-AKT. Myr-AKT overexpression reversed SPARC-mediated PTEN and increased proliferation of neuroblastoma cells in vitro. PTEN overexpression in parallel with SPARC siRNA resulted in decreased AKT phosphorylation and proliferation in vitro. Taken together, these results establish SPARC as an effector of AKT-PTEN-mediated inhibition of proliferation in neuroblastoma in vitro and in vivo
