On the troll line investigations off Cochin during five fishing seasons. Pt. 2. Investigations during 1963-64 season

During this season the investigations were mainly directed towards elucidation of the selective action of trolling lures. Feather jigs, buffalo horn jigs, stainless steel jigs, Japanese whale bone jigs and plastic jigs were selected. Operations were carried out from Fisheries technology No. 5

On the selective action of the cod end meshes of a shrimp trawl

Selectivity studies using cod end and cover to determine the optimum cod end mesh size for commercial size groups of shrimps was carried out at Cochin during 1963-64 fishing season. The normality of the result was checked by trouser cod end method. Although the present investigation was mainly aimed to find out suitable cod end mesh size for commercial varieties of shrimps, five commonly occurring species of fishes were also taken. The 50% escape level, co-efficient of selectivity and selection factor for all the species were worked out. From the findings, the authors stress the necessity of increasing the cod end mesh size from the present condition (25.4 to 31.70 mm) to 41.65 mm fabricated mesh size to avoid depletion of the natural population

The Role of Pelvic Neurophysiology Testing in the Assessment of Patients with Voiding Dysfunction

PURPOSE OF REVIEW: The role of pelvic neurophysiology testing in the evaluation of patients with lower urinary tract (LUT) symptoms is explored in this review. RECENT FINDINGS: Different neurophysiology tests such as sphincter EMG and pudendal somatosensory evoked potentials are useful in evaluating the sacral somatic afferent and efferent innervation. S2 and S3 dermatomal evoked potentials assess individual sacral roots and are feasible to perform using standard neurophysiology machines. SUMMARY: The innervation of the LUT has a substantial contribution from splanchnic and somatic nerves arising from the sacral segments. Pelvic neurophysiology tests, which assess somatic nerve functions, are therefore a useful tool in assessing sacral nerve functions in patients presenting with unexplained voiding dysfunction. In this review, the commonly performed neurophysiology studies that assess the S2, S3 and S4 sacral afferent and efferent pathways are outlined, and their clinical applications reviewed

Botulinum toxin-A for the treatment of overactive bladder: UK contributions

Background: Botulinum toxin-A (BoNT/A) is now established second-line management for refractory overactivebladder (OAB) and recognised in many incontinence guidelines and pathways. For those with neurogenic detrusoroveractivity secondary to spinal cord injury or multiple sclerosis, the toxin is currently licensed in certain parts of theworld, including the UK. It is an effective treatment in those in whom antimuscarinics and conservative measures havefailed who have symptoms of OAB and or detrusor overactivity (DO). Methods: Treatment can be given in an outpatient setting and can be administered under local anaesthesia. Its efficacylasts for between six and 12 months. Results: It has an acceptable safety profile with the biggest risk being urinary tract infection and difficulty emptying thebladder, necessitating clean intermittent self-catheterisation (CISC). Medium-term follow-up suggests repeated injectionsare also safe and efficacious. Conclusions: The mechanism of action of the toxin is more complicated than originally thought, and it seems likelythat it affects motor and sensory nerves of the bladder. In the last 10 years much of the progress of this treatment fromearly experimental trials to mainstream clinical use, and a better understanding of how it works in the bladder, are as aresult of research conducted in the UK. This review summarises the significant and substantial evidence for BoNT/A totreat refractory OAB from UK centres. © British Association of Urological Surgeons 2013

La singularidad de la farmacognosia clínica hindú en adición al rol de la fitoquímica estructural

There are two conceptually divergent streams of therapeutic modules operative in India today both being vibrant. These modules are operative on one hand in the modern hospitals as Allopathic system and the other being scattered in the country especially in the rural parts as Ayurvedic, Sidha and Unani and to an extent the century and half old Homeopathic systems. This review is to probe the possibility of converging the conceptually different systems under a single roof of modern hospital, the rendezvous achieved by the role of a Clinical Pharmacognosist who could bridge the gap between both the systems

COVID-19 and fear processing

The world faces a global crisis that encompasses health, financial, and psychological aspects as a result of the coronavirus disease. While the health crisis is significant, it is important to recognize that the human and social crises that have emerged are equally impactful. These crises have resulted in various negative outcomes, such as social rejection, economic disparity, unemployment, and mental distress. Fear is a significant psychological barrier that can impede recovery from any disease process, and thus, it plays a critical role in determining the mortality and morbidity of any given disease. The COVID-19 pandemic has generated a pervasive fear of infection that has further exacerbated the situation. This study explored the mechanisms by which humans may have elicited conditional fear, using the COVID-19 pandemic as a specific case study. Our goal was to examine the process of fear in humans by exploring our knowledge of neuroanatomy and the systemic response regulated by the autonomic nervous system

Identification and sequence analysis of Tapasin gene in guinea fowl

Abstract Aim: An attempt has been made to identify and study the nucleotide sequence variability in exon 5 -exon 6 regions of guinea fowl Tapasin gene. Materials and Methods: Blood samples were collected from randomly selected birds (12 guinea fowl birds) and Tapasin gene amplified using chicken specific primers designed from GenBank submitted sequences. Polymerase chain reaction conditions were standardized so as get only single amplicons. Obtained products were then cloned and sequenced; sequences were then analyzed using suitable software. Results: Amplicon size of the Tapasin gene in guinea fowl was same as reported in chicken with areas of transitions and transversions. The sequence variations reported in these coding sequences might have influence in the protein structure, which may be correlated with the increased immune status of the bird when compared with chicken breeds

Chemical composition and isotopic signatures of ice and snow over a Himalayan Glacier (Satopanth) in India

This study reports the chemical composition and isotopic signatures of snow and ice over a Himalayan Glacier in India. An observational campaign was carried out from September 22, 2016, to October 2, 2016, over Satopanth in central Himalaya. The pH value of ice and snow, respectively, was 5.6 ± 0.4 and 5.9 ± 0.35 over the glacier, indicating moderate acidity of the glacier components. Calcium (Ca2+) was the dominant component in snow (35.2%), while sulfate (SO42−) was dominant in ice samples (52.7%). The neutralization factor was estimated to find the extent of neutralization of acidic fractions by basic components. It is found that Ca2+ was the prominent neutralizing factor both in snow and ice over the region. Oxygen and hydrogen isotopic analyses of snow, surface layer ice and debris-covered ice suggest that the moisture source is common for all three components. δD and d-excess values of snow at Satopanth are different than that of those for Chorabari, Dokriani and Tiprabank Glacier, indicating the plausibility of different sources of moisture for these glaciers. Limited observations suggest that the interaction of ice with the debris has no impact on the isotopic signatures of the ice over the region; such non-alteration of isotopic signatures makes the region important for ice core-based paleoclimatic studies
