Performance of parthenocarpic and non-parthenocarpic grafts of cucumber

Effect of rootstock on yield and quality of cucumber scion was studied at Department of Vegetable Science, College of Agriculture, Vellayani, Thiruvananthapuram, Kerala during February-May, 2021. Parthenocarpic and non-parthenocarpic cucumber scions were grafted onto five different cultivated cucurbit species i.e. pumpkin, bottle gourd, oriental pickling melon, culinary melon and ash gourd. Significant variations were observed for all the traits under this study. The highest vine length (4.37 m) was observed in Heera scion grafted onto Lagenaria siceraria rootstock followed by Heera scion grafted onto Cucurbita moschata rootstock (4.13 m). The diameter of rootstock hypocotyl was higher in case of KPCH-1 grafted onto bottle gourd (1.48 mm) and Heera grafted onto bottle gourd (1.43 mm). KPCH-1 grafted on bottle gourd (29.33 days) and culinary melon (31 days) rootstocks showed early female flower initiation. The greater number of fruits was observed in graft combination of KPCH- 1 and bottle gourd (32) followed by parthenocarpic grafts with pumpkin (30.33) and ash gourd (30.33) rootstocks. A greater fruit weight was observed in graft combination of Heera and bottle gourd (7.51 kg) followed by Heera grafted onto pumpkin (7.38 kg). Results of this experiment suggest that these graft combinations can be employed in sustainable vegetable cultivation

Impact of Mass Bathing and Religious Activities on Water Quality Index of Prominent Water Bodies: A Multilocation Study in Haryana, India

The present study was designed to assess the impact of mass bathing and religious activities on water quality index (WQI) of prominent water bodies (eight) in Haryana, India. Water quality characteristics revealed significant increase in the values of nitrate, biochemical oxygen demand (BOD), turbidity, total dissolved solids (TDS), conductivity, total hardness, total alkalinity, and MPN count after the religious activities. The computed WQI at all the eight selected sites varied from 47.55 to 211.42. The results revealed that there was a significant increase in the value of WQI after mass bathing or any other ritual performed. Out of eight water bodies studied three (sites 3, 4, and 5) were found under good water quality status; four sites (1, 2, 6, and 7) depicted medium water quality but site 8 was found under poor water quality after the religious activities. The good water quality status of water bodies was correlated with larger size of the water bodies and less number of pilgrims; however, the poor WQI values may be attributed to smaller size of the water body and heavy load of pilgrims on such sites. Therefore, water of these religious water bodies needed to be regularly changed after mass bathing to protect the aquatic component from different contaminations

Interventional study to find out effect of human chorionic gonadotropin and antioxidants on idiopathic male infertility

Background: Male contributes about 50% for cases with combined male and female infertility. When the cause is not known, it is term as idiopathic infertility. It affects 25% of men. Many advances have been made in reproductive medicine which provides great opportunities, couples which were considered untreatable now have got chance to have their own babies. Various ART procedures like ICSI have been proven as an efficient therapy in severe male factor infertility. However, the cost per cycle and complications such as multiple gestations cannot be ignored. Medical management of infertility can be specific or empirical depending on etiology. Specific medical management is use when certain etiology is identified. However, in absence of specific etiology use of empirical medical treatment can be attempted in order to improve treatment results. In this study our aim is to evaluate the effect of human chorionic gonadotropin (hCG) and antioxidants on semen parameters in men with idiopathic male infertility.Methods: Thirty men with abnormal semen parameters were included in study. Patients were treated with injection hCG-2000 IU three times a week for three months along with the antioxidants. After 3 months of treatment repeat semen analysis were performed and results were compared with pre-treated seminal parameters.Results: Results showed significant increase in sperm count (p value ≤ 0.001), total motility (p value=<0.001), and progressive forward motility (p value = <0.001), while no significant difference is seen in rest of the parameters.Conclusions: Use of hCG and antioxidants in idiopathic male infertility can significantly improve seminal parameters in idiopathic male infertility

ASSESSING THE COMPETING ABILITY OF WEEDY RICE (Oryza sativa f. spontanea) WITH CULTIVATED RICE UNDER ELEVATED CO2 CONDITIONS

Climate change can adversely affect rice production, especially for weed management in the context of emergence and proliferation of newer weed species like weedy rice (Oryza sativa f. spontanea) in the rice growing tracts of Kerala. In the past decade, atmospheric carbon dioxide (CO2) has risen from 371.82 to 407.05 ppm from 2000 to 2018 which might have an impact on the competitive ability of a C3 plant like weedy rice. The competitiveness of weedy rice was studied in an open top chamber (OTC) under a CO2 concentration of 500 ppm (Chamber A), OTC without external CO2 supply (Chamber B), and open condition along with two popular cultivated rice varieties Uma and Jyothi with both air and soil temperature inside the chamber to the tune of 40-430C and 35-400C respectively. The study revealed a higher competitive potential of weedy rice in terms of tillering ability under elevated carbon dioxide as it responded well compared to cultivated rice varieties. There was a differential response of rice varieties to elevated CO2 conditions with medium duration variety responding well compared to short duration one. Compared to ambient conditions (chamber B and open condition), higher tillering was observed under elevated CO2 (chamber A) in which weedy rice tillered profusely (17.33) than cultivated rice species (9 and 11.33). There was a linear increase in plant height of weedy rice in chamber A (108.97 cm) during the initial stages and in chamber B (112.77 cm) during reproductive stages. The study evidenced that in the coming future, higher CO2 levels can stimulate biomass production of C3 weed like weedy rice with a greater increase in tillering which could be an important trait affecting inter specific competition

Practice patterns for acute ischemic stroke workup: A longitudinal population‐based study

Background We examined practice patterns of inpatient testing to identify stroke etiologies and treatable risk factors for acute ischemic stroke recurrence. Methods and Results We identified stroke cases and related diagnostic testing from four 1‐year study periods (July 1993 to June 1994, 1999, 2005, and 2010) of the Greater Cincinnati/Northern Kentucky Stroke Study. Patients aged ≥18 years were included. We focused on evaluation of extracranial arteries for carotid stenosis and assessment of atrial fibrillation because randomized controlled trials supported treatment of these conditions for stroke prevention across all 4 study periods. In each study period, we also recorded stroke etiology, as determined by diagnostic testing and physician adjudication. An increasing proportion of stroke patients received assessment of both extracranial arteries and the heart over time (50%, 58%, 74%, and 78% in the 1993–1994, 1999, 2005, and 2010 periods, respectively; P &lt;0.0001 for trend), with the most dramatic individual increases in echocardiography (57%, 63%, 77%, and 83%, respectively). Concurrently, we observed a decrease in strokes of unknown etiology (47%, 48%, 41%, and 38%, respectively; P &lt;0.0001 for trend). We also found a significant increase in strokes of other known causes (32%, 25%, 45% and 59%, respectively; P &lt;0.0001 for trend). Conclusions Stroke workup for treatable causes of stroke are being used more frequently over time, and this is associated with a decrease in cryptogenic strokes. Future study of whether better determination of treatable stroke etiologies translates to a decrease in stroke recurrence at the population level will be essential. </jats:sec

MitoNeoD:a mitochondria-targeted superoxide probe

Mitochondrial superoxide (O2⋅−) underlies much oxidative damage and redox signaling. Fluorescent probes can detect O2⋅−, but are of limited applicability in vivo, while in cells their usefulness is constrained by side reactions and DNA intercalation. To overcome these limitations, we developed a dual-purpose mitochondrial O2⋅− probe, MitoNeoD, which can assess O2⋅− changes in vivo by mass spectrometry and in vitro by fluorescence. MitoNeoD comprises a O2⋅−-sensitive reduced phenanthridinium moiety modified to prevent DNA intercalation, as well as a carbon-deuterium bond to enhance its selectivity for O2⋅− over non-specific oxidation, and a triphenylphosphonium lipophilic cation moiety leading to the rapid accumulation within mitochondria. We demonstrated that MitoNeoD was a versatile and robust probe to assess changes in mitochondrial O2⋅− from isolated mitochondria to animal models, thus offering a way to examine the many roles of mitochondrial O2⋅−production in health and disease

Regular Antenatal Care Visits Predict Good Knowledge Among Post-natal Mothers Regarding Entitlements of Health Programs in Western India

Janani-Shishu Suraksha Karyakram (JSSK) and Janani Suraksha Yojana (JSY) were launched with the objective of increasing institutional deliveries. But, its knowledge among the post-natal mothers is not known. This research evaluated the knowledge of two national health programs among post-natal mothers and found out the predictors of good knowledge about the entitlements of these programs. A cross-sectional study was conducted on a sample of consecutively recruited 339 post-natal mothers who had delivered in a tertiary care hospital of western India. Data were collected from November 2016 to February 2017 by interview method using a questionnaire with questions about knowledge regarding the entitlements of JSSK and JSY. Multivariable analysis was carried out for predictors of good knowledge. Among the 339 post-natal mothers, 30% had a good knowledge regarding JSSK. Only 24% had heard about JSSK; 54% knew regarding free transport to the place of delivery; only 22% and 13%, respectively knew about free inter-facility transport in case of complications for pregnant women and sick infants, while 96% knew regarding free drop-back facility. Only one-fourth of the mothers knew regarding monetary benefit under JSY, while 28% of them had actually received the benefit. The number of antenatal care visits, having an occupation and belonging to Hindu religion significantly predicts good knowledge among postnatal mothers regarding JSSK. Knowledge among the post-natal mothers regarding the entitlements of JSSK and JSY is less while comparing with published literature and needs improvement. Regular ante-natal care (ANC) visits might improve their knowledge of these programs. There is a need to create awareness among hospital staff for the provision of reimbursement of costs incurred by post-natal mothers. There is also a need to carry out demand generation activities among mothers regarding the entitlements of JSSK and JSY

Engaging Emergency Department Patients in the Creation of a Shared Decision-­Making Tool Regarding CT Scanning in Kidney Stones: Challenges to Traditional Stakeholder Engagement

Background: Every year approximately 2 million patients are seen in US EDs for suspected renal colic, and the majority receive CT scans. The objective of our study was to develop a stakeholder-informed conversation aid to help clinicians use SDM regarding CT scanning in patients with suspected renal colic. Methods: Using a published decision aid development framework, and under the direction of a multi-disciplinary Steering Committee, we engaged a diverse set of stakeholders via qualitative methods. EM clinicians, urologists, radiologists, researchers, and emergency department patients participated in focus groups and semi-structured interviews. All groups were recorded, transcribed, and analyzed in an iterative process by a four-person coding team. Emergent themes were identified and used to develop a decision aid which was iteratively refined. Results: A total of 8 interviews and 7 focus groups were conducted with 36 stakeholders (including local ED patients) The following three themes emerged: 1. Patient participants reported a desire to be involved in this decision and wanted more information regarding risks and benefits of CT scans. 2. Clinicians were comfortable diagnosing kidney stones without a CT scan, however, some felt that clinical uncertainty was a barrier to SDM. 3. All stakeholders identified strategies to facilitate this conversation such as check-lists and visual aids. Conclusion: Using stakeholder input, we developed a communication tool to facilitate an SDM conversation around the use of CT in suspected renal colic. Further testing will assess whether this tool can safely improve patient engagement and decrease low yield CT usage
