Background: Knowledge of plant population structure facilitates conservation, management, and utilization of endangered plants.
Research question: What is the current status of the natural populations of Tetracentron sinense in Leigong Mountain Nature Reserve (LMNR) and what future population development trends can be predicted?
Studied species: Tetracentron sinense
Study site and period of research: T. sinense populations in LMNR in China in 2018.
Methods: The population structure and quantity dynamics of four typical patches were studied using static life tables, survival curves, survival analyses, and time series analyses.
Results: The age structures of the T. sinense populations were spindle-shaped, with few seedlings and saplings, and Deevey type II and ? survival curves. The mortality rate ( q x ) of each patch increased quickly, and then plateaued, finally increasing again. Survival rate ( S x ) showed a contrary trend to q x . Trends in cumulative mortality rate ( F (i) ), killing power ( K x ), mortality density ( f (ti) ), and hazard rate ( ? (ti) ) with increasing age class were similar: increasing at a younger age, gradually stabilizing in middle age, and then increasing slightly in older age. The number of individuals in these T. sinense populations was predicted to decrease sharply in future, with younger individuals being seriously deficient. The results showed that the natural populations of T. sinense in the LMNR were relatively stable but were in an early stage of decline.
Conclusions: The lack of younger individuals might reflect a bottleneck for regeneration of T. sinense populations , leading to a decline in population size.

Antecedentes: Es importante entender las prácticas agrícolas y los criterios de selección que moldean la diversidad de variedades locales en plantas domesticadas. La región andina comparte con la región mesoamericana y Norteamérica los centros de origen de las cinco especies domesticadas de Cucurbita . Sin embargo, los estudios sobre diversidad biológica de estas especies son escasos en Perú en comparación con México.
Preguntas: ¿Cuáles son las variedades locales de Cucurbita que reconocen, promueven y conservan los agricultores en el Distrito de Tomayquichua? ¿Qué mecanismos promueven la diversidad de estas variedades?
Especies estudiadas: Cucurbita ficifolia Bouché, Cucurbita moschata Duchesne, Cucurbita maxima Duchesne.
Sitio y año de estudio: Tomayquichua, Huánuco, Perú (junio de 2018 y 2019).
Métodos: Se realizaron entrevistas semiestructuradas a 29 familias de agricultores y comerciantes para evaluar la diversidad de variedades locales y las prácticas de manejo de las especies del género Cucurbita .
Resultados: C. ficifolia es la cucurbitácea más diversa en Tomayquichua (13 variedades) seguido de C. moschata (10 variedades), las cuales se siembran en chacras y traspatios. Se reportan siete variedades de C. maxima , con el uso predominante de una variedad comercial en cultivos intensivos.
Conclusión: Las prácticas agrícolas tradicionales parecen mantener la diversidad local de C. ficifolia y C. moschata . Las variedades locales de C. maxima en Tomayquichua parecen ser desplazadas progresivamente por una variedad mejorada destinada a aumentar la producción mediante prácticas agrícolas intensivas. La alta diversidad biológica de C. ficifolia en Perú sugiere un origen andino, pero se requieren estudios genéticos adicionales para aclararlo.

An inclusive study of relationship between lengths of hand and its correlation to height of person provides valuable help in generating biometric database. Limited research exists on morphometric assessment of hand dimensions in Indian population. The objective of the current study was to frame the morphometric database of hand measurements in context of its clinical implications. The generated data can be used in various anthropological studies. A Cross-sectional Indian population-based study was carried out among 500 male and female healthy students after excluding past history of trauma or illness after taking written, informed consent. Hand dimensions were measured by ‘Rod Compass’. The data was processed and analysed in SPSS Version 20 (SPSS Inc., Chicago, IL, USA). Two tailed ‘p’ value of 0.05 was taken as statistically significant. Appropriate statistical tests of significance, correlation coefficients, and multiple regression correlations were computed to evaluate statistical differences. The mean hand length in the females was lower as compared to males who had significantly higher mean hand length in all age groups. The difference was found to be statistically significant (p&#60;0.001). The study revealed positive relationship between hand length and height. Hand dimensions provide good reliability in estimation of stature. This biometric data can be successfully utilized in management of various health ailments.

Heart rate variability is one of the diagnostic tests to assess the autonomic dysfunction in type 2 Diabetes Mellitus. To compare the heart rate variability (HRV) and classical autonomic function tests between type 2 DM and healthy volunteers. This study was conducted in 30 type 2 Diabetes mellitus patients and 30 healthy volunteers. Average age of diabetic patients was 48.53±5.12 (mean ± SD) and that of volunteers was 47.10±3.59 (mean ± SD). ECG recording was done in supine position for 5 minutes in computerized physiography. HRV analysis was done using Finland software. Classical autonomic function parameters such as deep breathing difference test, heart rate and blood pressure response to hand grip dynamometer test and valsalva ratio test were recorded in them. Statistical analysis was done using student’s t-test. HRV showed statistically significant impairment between cases and controls (p&#60;0.05). Classical autonomic function test showed statistically very significant impairment between cases and controls (p&#60;0.0001). HRV and Classical autonomic function tests reveals autonomic impairment in Type 2 DM, but classical autonomic function test findings showed very significant (P&#60;0.0001) impairment than HRV analysis (P&#60;0.05). So this study showed autonomic function tests are superior to HRV analysis.

Published: March 2020

Cadaveric dissection forms integral part of learning anatomy. Few students are actively involved in dissection and remaining are passive observers. Present study was conducted to compare students’ perception about cadaveric dissection practices following group dynamics [allotting a dissection-task related to each student] And effect of following group dynamics during cadaveric dissection on student's performance. Perception and performance in theory and practical assessments were compared between control group [not following group dynamics] and study group [following group dynamics]. Study group perceived following group dynamics has positive effect on learning and skill acquisition. Difference in performance was not significant in first theory assessment between study and control group, study group performed significantly better in both practical and second theory assessment. Group dynamics used during dissections help students perform better by understanding complex task by peer learning and feedback and also helps them to develop leadership, time management and communication skills.

Published: March 2020

Hypothyroidism has been steadily increasing all over the world among all the endocrine dysfunctions. Subclinical hypothyroidism being more common than overt hypothyroidism, affects 3–15% of the adult population. Its incidence increases with advanced age, female gender, and increased dietary iodine intake. To study the Pulmonary Function Tests in a group of newly diagnosed subclinical hypothyroid females and to compare the Pulmonary Function Tests in subclinical hypothyroid females with controls. The present study was undertaken in the Department of Physiology, KIMS, Hubballi. Thirty females with newly diagnosed subclinical hypothyroidism, without any pre-existing cardio pulmonary disorders in the age group of 20-40 years, residing in and around Hubballi city served as study subjects. Another group of 30 females, who were similar to study group but healthy persons, were taken from the staff and friends, served as control group. In the present study Lung function data were collected using the ndd EasyOn Spirometer (ndd Medical Technologies, Zurich, Switzerland). Clinical, biochemical & spirometry data were analysed using statistical software, ‘Graphpad – Quickcals’. FVC, FEV1, FEV1/FVC, FEF25-75%, and PEF of spirometry showed significant decrease in subjects as compared to controls.In the present study Spirometry changes in subclinical hypothyroidism cases included significant decrease in the parameters like FVC, FEV1, FEV1/FVC, FEF25-75%, and PEF compared to controls. This could be because of muscular dysfunction, fatigue and somnolence which have proved to exist in SCH subjects.

The spleen is a largest collection of lymphoid tissue with diverse hemopoietic and phagocytic function. Recent experimental data have clearly defined immunological functions of spleen in innate and adaptive immunity, as a frontline of host defense against various infections. A comprehensive knowledge of splenic anatomical variations and morphometric dimensions is crucial in deciphering the role of spleen in health & infirmity. The aim of the study is to perform detailed morphometric analysis human splenic specimens with relation to age & gender differences and compare the findings with earlier studies. The present study included 40 cadaveric spleen and morphometric features i.e., length, breadth, width and weight of spleen were measured. The average splenic weight observed was 178.5 gm and range was 100 to 300 gm. The average length, breadth and width of spleen were 11.9 cm, 7.33 cm and 3.4 cm respectively. The average splenic volume in the present study was 167.27 cc. There was a significant increase in splenic volume till 40-49 years followed by steady decline. The awareness of the morphology and dimensions of the spleen is of fundamental importance to the hematologists, clinicians, radiologists, prosectors and surgeons while performing surgical procedures on spleen.

Cervical myelopathy a debilitating degenerative condition occurs due to cervical spinal canal stenosis, the incidence of which increases significantly with age and is more common above the age of 50 years. Imaging of the spinal canal is an indispensable procedure for evaluation of cervical myelopathy and standard lateral radiographs remain the recommended initial imaging study of choice. The present study was undertaken to measure the cervical spinal canal diameter by lateral radiographs of the cervical spine and to study the degree of cervical spinal canal stenosis in symptomatic patients and asymptomatic cases. The canal body ratio and its reliability to assess cervical spinal canal stenosis and risk of cervical myelopathy was evaluated.In this study 200 cases who presented to the radiology department for radiographs of cervical spine, were divided into symptomatic and asymptomatic cases and were grouped age wise. Measurements of the cervical vertebral body and cervical spinal canal were taken. Torg ratio was assessed. The measurements were analyzed statistically and results tabulated.Cervical spinal canal diameter was lower in symptomatic cases as compared to asymptomatic cases across all age groups and the lowest value was measured at C3 level. All the symptomatic cases had Torg ratio of less than 0.82, and that of C3 was lowest. The data analysis showed the sensitivity of the Torg ratio as 100%. 40% of patients above 50 years were symptomatic and had cervical spinal canal stenosis on lateral radiographs.Our results suggest that plain films can estimate the cervical spinal canal midsagittal diameter and be used as a first step examination for the evaluation of cervical spinal stenosis. The importance of canal body ratio in lateral cervical radiographs for determining the stenosis of cervical spinal canal is confirmed.

Optimal stimulation of vestibular system has more soothing effects and is essential throughout the life. Though there are different methods like running, swinging, dancing, jumping to stimulate vestibular system, swinging on a swing is a simple method to stimulate vestibular system, which was an ancient practice incorporated in Indian tradition.The aim of this research was to assess the effect of vestibular stimulation on selected biochemical parameters in young adults.A total of 300 (130 males and 170 females) young adults were screened. 240 (120 males and 120 females) participants satisfying both inclusion and exclusion criteria were included in the study. This was a longitudinal follow-up study in which, participants were assessed three times. The first assessment was performed during regular classes (with no examination in preceding two weeks and forth coming two weeks), these are pre-intervention values. The second assessment was performed eight months after the intervention (during regular classes), and third assessment was performed sixteen months after the intervention in stressed state (A week before the University examinations).The mean salivary IgA in the experimental female group was 61µg/mL. After 8 months, there was a slight increase in salivary IgA whereas after 16 months also there was a slight increase in salivary IgA. The mean salivary α amylase in experimental female group was 84 U/ mL. After 8 months, there was a slight decrease in salivary α amylase whereas after 16 months also, there was a slight decrease in salivary α-amylase.The present study results support positive impact of stimulation of vestibular system using natural methods like swinging on a swing that exists as day to day activity in the tradition of India. The study recommends using the swing in routine life style for better wellbeing.
Comparative study of intraocular pressure measured by non-contact, rebound and goldmann applanation tonometer and their correlation with corneal thickness and true IOP in a general population
Authors: Das Santanu , Kumar L Kiran 
Published: March 2020

: To compare the Intraocular Pressure (IOP) measured by Non-contact tonometer (NCT), Rebound tonometer (RBT) and Goldmann Applanation tonometer (GAT) and their correlation with central corneal thickness (CCT) and true IOP.Reliability of each tonometer. 500 random patients aged 18 years and above were taken up for the study. Patients with anterior and posterior segment pathologies like corneal ulcer, leukoma, staphyloma, corneal lacerations, ectatic corneal conditions, corneal dystrophies, oedema, perforations, acute angle closure glaucoma, retinal detachments, vitreous haemorrhage and unwilling patients were excluded from the study. IOP was recorded using NCT, RBT and GAT after assessing the patient's visual acuity. Following IOP measurement, central corneal thickness (CCT) of each patient was measured using pachymetry. All the data were collected and tabulated for statistical analysis to obtain results. The mean CCT in males was 0.5350 mm and in females 0.5340 mm respectively. The mean IOP measured by NCT is 16.43 mm hg whereas the mean IOP measured by GAT is 15.43 mm hg. IOP measured by NCT is significantly higher than the IOP measured by GAT (p&#60;0.001). When NCT and RBT are compared NCT values are significantly higher than that of RBT(p&#60;0.001). Although the mean RBT IOP 15.83 mm hg is higher than the mean GAT IOP of 15.42 mm hg the values are not statistically significant. When correlated with CCT all the tonometers showed significant correlation with GAT showing the strongest correlation. NCT overestimates IOP in normal, thin and thicker corneas when compared to GAT and are statistically significant. RBT also overestimates in the normal and thick corneas when compared to GAT but their values are much closer to GAT values in thinner corneas. The IOP measured by all the 3 tonometers correlated with corrected IOP with NCT showing the best correlation followed by GAT. From the present study we can conclude that IOP measured by NCT and RBT is higher than GAT. NCT values are significantly higher than GAT values in thin and normal corneas whereas it overestimates more in thicker corneas. RBT values are significantly higher than that of GAT in normal and thick corneas. So, it is always advisable to measure the corrected IOP for each patient after considering the CCT.
