Maize is affected by drought and heat, abiotic stress factors that have been encountered more often in recent years in various parts of Europe. In the area of Turda, Romania, extreme temperatures and heat waves combined with an uneven distribution of precipitation have been recorded that had an unfavorable influence on the maize crop. In this study, the ASI (anthesis-to-silking interval), yield, and stability of 35 old and new maize hybrids created at the Agricultural Research and Development Station Turda were studied under drought and heat conditions.

Traumatic Brain Injury (TBI) is a global healthcare concern with considerable mortality and morbidity. Early diagnosis and timely treatment are critical for optimal clinical prognosis in TBI patients. Injury to the brain tissue following TBI is categorized into primary and secondary injury events, with the former being acute, while the latter evolves over a long period.

Article Synopsis
  • A pilot study was conducted to evaluate the effectiveness of noradrenaline versus adrenaline in treating neonatal septic shock at a NICU from August 2020 to January 2022.
  • Key findings showed that after one hour, 76.2% of neonates in the noradrenaline group had resolution of shock compared to 61.9% in the adrenaline group, with similar mortality rates of 28.6% and 33.3%, respectively.
  • Additionally, the noradrenaline group required fewer additional vasopressors and had a shorter median ICU stay (6 days) compared to the adrenaline group (10 days).

Article Synopsis
  • The study examines the outcomes of left atrioventricular valve (LAVV) operations in patients with atrioventricular septal defects (AVSD) over a 20-year period, highlighting the challenges and complications involved.
  • Out of 843 patients with repaired AVSDs, 59 (7.3%) underwent LAVV operations, with notable rates of reoperation and valve replacement among them, particularly in those who had complex repairs.
  • Key risk factors for adverse events included having a lower body weight and needing early LAVV surgery, while cleft closure during initial surgery appeared to provide some protective benefits.

The iPSC line NIMHi013-A was generated from peripheral blood mononuclear cells of a paediatric patient with drug resistant epilepsy. The proband was found to have a likely pathogenic missense variant in the SCN1A gene in heterozygous state, which segregated in the affected in dominant fashion. The variant is in the Nav1.

Article Synopsis
  • Long-term enlargement of the aortic arch after reconstruction in patients with hypoplastic left heart syndrome (HLHS) was studied using measurements from 50 patients who underwent Fontan completion.* -
  • Over time, the dimensions of the aortic arch increased significantly after reconstruction, with peak enlargement typically occurring around 7 to 12 months post-surgery, followed by a gradual decline in growth into adolescence.* -
  • Both Norwood and hybrid surgical strategies resulted in similar patterns of aortic arch enlargement, suggesting the need to investigate surgical factors that could optimize growth outcomes.*

Diet significantly affects reproductive outcomes across species, yet the precise effects of macronutrient compositions beyond caloric intake on reproductive aging are understudied. Existing literature presents conflicting views on the fertility impacts of nutrient-rich versus nutrient-poor developmental diets, underscoring a notable research gap. This study addresses these gaps by examining effects of isocaloric diets with varied protein-to-carbohydrate ratios during both developmental and adult stages on reproductive aging of a large, outbred Drosophila melanogaster population (n = ∼2100).

Article Synopsis
  • A neonate exhibited symptoms of abdominal swelling and less urination, leading to a diagnostic X-ray.
  • The X-ray indicated the presence of ascites and a distended bladder, alongside spinal deformities, suggesting urinary ascites and a neurogenic bladder.
  • The report highlights the importance of abdominal X-rays in diagnosing such rare medical conditions and discusses the clinical findings, diagnostic methods, and treatment options.

Article Synopsis
  • * A study included 25 patients aged around 6 months, with a mortality rate of 8.3% at 6 months and 17.6% at 5 years; nearly 50% of patients required a mechanical valve replacement within 3.5 years.
  • * Complications like bleeding and thrombosis were low (87.5% freedom rate at 4 years), and early functional deterioration may require repeat surgeries, which can be performed safely.

The main aim of this article is to highlight the clinical features indicating gastric perforation in neonates so that prompt surgery can provide a good outcome for an otherwise fatal condition. Data was collected retrospectively from all neonates who presented to our tertiary care institute with subsequent diagnosis of gastric perforation from January 2020 to December 2023 (three years). Simple statistical analysis involving sums, means, averages, and percentages was used.

With the advancements in the medical field, many innovations in medical devices have happened. Using a surgical stapler to close the laryngectomy defect without opening the pharynx is particularly advantageous in a total laryngectomy (TL). However, performing the tracheoesophageal puncture (TEP) during stapler closure of the larynx has not been widely advocated, due to the fear of complications related to the procedure.

Background: As the global battle against the COVID-19 pandemic endures, the spread of the Delta variant has introduced nuanced challenges, prompting a nuanced examination.

Materials And Methods: We performed a multilevel logistic regression analysis encompassing 197 patients, comprising 44 vaccinated individuals (V group) and 153 unvaccinated counterparts (UV). These patients, afflicted with the Delta variant of SARS-CoV-2, were hospitalized between October 2021 and February 2022 at the COVID-19 department of a University Centre in Cluj-Napoca, Romania.

Objective: Fetuses with single ventricle physiology (SVP) exhibit reductions in fetal cerebral oxygenation, with associated delays in fetal brain growth and neurodevelopmental outcomes. Maternal supplemental oxygen (MSO) has been proposed to improve fetal brain growth, but current evidence on dosing, candidacy and outcomes is limited. In this pilot study, we evaluated the safety and feasibility of continuous low-dose MSO in the setting of SVP.

The analysis of hydrocarbon biomarkers in surface sediments along the Markanda River in the foothills of the Indian Himalayas was conducted to gain insights into the distribution and composition of organic matter (OM) within the sediments. This investigation is essential for comprehending how anthropogenic changes are influencing the OM dynamics in river systems. The study involved identification and quantification of various compound groups such as n-alkanes, hopanes, steranes, polycyclic aromatic hydrocarbons (PAHs), linear alkyl benzenes (LABs) and phthalate esters along with their respective parametric ratios.

Background: Biocontrol is regarded as a viable alternate technique for managing sugarcane wilt disease caused by Fusarium sacchari. Many fungal antagonists against F. sacchari, have been reported, but the potential of bacterial antagonists was explored to a limited extent, so the present study evaluated the antagonistic potential of rhizoplane Bacillus species and their mode of action.

Background: There are limited global data on head-to-head comparisons of vaccine platforms assessing both humoral and cellular immune responses, stratified by pre-vaccination serostatus. The COVID-19 vaccination drive for the Indian population in the age group 18-45 years began in April 2021 when seropositivity rates in the general population were rising due to the delta wave of COVID-19 pandemic during April-May 2021.

Methods: Between June 30, 2021, and Jan 28, 2022, we enrolled 691 participants in the age group 18-45 years across four clinical sites in India.

In this study, we have established human induced pluripotent stem cell (hiPSC) line, NIMHi010-A of a 42-year-old healthy donor. The iPSC line was generated from human dermal fibroblasts using Sendai viruses carrying reprogramming factors c-MYC, SOX2, KLF4, and OCT4 under a feeder-free culture system. The generated hiPSC line expressed typical pluripotency markers, displayed a normal karyotype, and demonstrated the potential to differentiate into the three germ layers.

This is a reflection on the nature of language used by psychologists in the contexts of referrals and assessments. Through an example of a brief referral, I attempt to unpack the "clinical" language that may dehumanise and pathologise individuals. Further, I attempt to reframe it through a language, that is not just a shift from "deficits" to "strengths", rather a discourse respecting personhood.
