Spiradenocylindroma is a rare benign adnexal tumor with features of both spiradenoma and cylindroma, the scalp and face being the most common sites. They are considered to arise from pluripotent cells of abortive adnexal primordial tissue. Fine needle aspiration cytology, along with cell block, can give clues regarding the diagnosis.

Although copper catalysts have been widely employed in various catalytic transformations, their potential for converting CO to methanol remains largely unexplored to date. Herein, it is reported that a copper(I) salt efficiently converts CO into methanol equivalent in the presence of NaBH and an amide ligand (L1) under mild reaction conditions. The in situ generated active catalyst in the reaction is isolated as a single crystal and the structure solution reveals the formation of a reactive two-coordinate Cu(I) dimeric catalyst [Li(THF)Cu(L1)] (1).

Apple stem grooving virus (ASGV) is an important pathogen with a broad host range, infecting both monocot and dicot species, making it a promising candidate for virus-induced gene silencing (VIGS) applications in functional genomics. In this study, we developed an infectious cDNA clone of an ASGV apple isolate and demonstrated its infectivity across 10 diverse plant species from families' including Solanaceae, Fabaceae, Cucurbitaceae, and Amaranthaceae. The clone also successfully infected woody hosts such as Citrus limon and Malus domestica, and resulted in systemic infection through back-inoculation in Cucumis sativus, thereby fulfilling Koch's postulates.

Stabilizing large easy-axis type magnetic anisotropy in molecular complexes is a challenging task, yet it is crucial for the development of information storage devices and applications in molecular spintronics. Achieving this requires a deep understanding of electronic structure and the relationships between structure and properties to develop magneto-structural correlations that are currently unexplored in the literature. Herein, a series of five-coordinate distorted square pyramidal Co complexes [Co(L)(X)].

Class I ribonucleotide reductases consisting of α and β subunits convert ribonucleoside diphosphates to deoxyribonucleoside diphosphates involving an intricate free radical mechanism. The generation of free radicals in the Class Ib ribonucleotide reductases is mediated by di-manganese ions in the β subunits and is externally assisted by flavodoxin-like NrdI subunit. This is unlike Class Ia ribonucleotide reductases, where the free radical generation is initiated at its di-iron centre in the β subunits with no external support from another subunit.

Article Synopsis
  • Plants rely on both abiotic factors (like temperature and water) and biotic interactions (with pathogens and symbiotic bacteria) for survival, and imbalance in these interactions can lead to stress and disease.
  • The text highlights the negative impact of viral infections on plants under abiotic stress while also emphasizing the positive role of root-associated symbiotic bacteria in supporting plant health.
  • It discusses the biochemical adaptations in plants due to bacterial symbiosis, and suggests exploring beneficial rhizospheric bacteria to improve plant health and manage abiotic stress in horticulture.

India has been a part of 5 major wars since its independence in 1947 and hosts over 212,413 refugees from Sri Lanka, Tibet and Bangladesh. So, a wide spectrum of trauma survivors, both civilian and military, live in this country and require mental healthcare. We discuss the psychological impact of armed conflict and how the country and culture tint it uniquely.

Article Synopsis
  • Plasma cell dyscrasias are serious conditions caused by abnormal plasma cells producing excessive monoclonal antibodies, leading to various health issues, including eye problems.
  • A comprehensive literature search was conducted in March 2021 to investigate ocular complications related to these disorders, which include conditions like multiple myeloma and POEMS syndrome.
  • Identifying eye symptoms is crucial for early diagnosis and treatment, highlighting the need for eye specialists and oncologists to be alert to these signs to prevent disease progression.

This study was conducted to assess the effect of two thermal treatments, viz. roasting and pan frying (deep frying), on nutritional profile, aflatoxin, and capsaicin content in green chilies. Green chilies were subjected to roasting and frying to reduce the aflatoxin contamination, besides retaining their pungency and nutritional profile.

Vitamin D's role in combating the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), the virus causing COVID-19, has been established in unveiling viable inhibitors of COVID-19. The current study investigated the role of pre and pro-vitamin D bioactives from edible mushrooms against Mpro and PLpro proteases of SARS-CoV-2 by computational experiments. The bioactives of mushrooms, specifically ergosterol (provitamin D), 7-dehydrocholesterol (provitamin-D), 22,23-dihydroergocalciferol (provitamin-D), cholecalciferol (vitamin-D), and ergocalciferol (vitamin D) were screened against Mpro and PLpro.

Article Synopsis
  • Marigold flower petals are a great source of lutein, beneficial for food and health, and this study focuses on using it to enhance sunflower oil's stability.
  • The extraction process was optimized with ultrasound-assisted extraction, revealing that the best results come from specific conditions involving ultrasonic intensity, time, and solid-to-solvent ratios.
  • Results showed that sunflower oil enriched with higher lutein levels had better oxidative stability compared to lower lutein levels and oil without lutein, indicating effective extraction and application for improving oil quality.

The role of N6-methyladenosine (mA) modifications has increasingly been associated with a diverse set of roles in modulating viruses and influencing the outcomes of viral infection. Here, we report that the landscape of mA deposition is drastically shifted during Kaposi's sarcoma-associated herpesvirus (KSHV) lytic infection for both viral and host transcripts. In line with previous reports, we also saw an overall decrease in host methylation in favor of viral messenger RNA (mRNA), along with 5' hypomethylation and 3' hypermethylation.

The catalytic domain of most 'cut and paste' DNA transposases have the canonical RNase-H fold, which is also shared by other polynucleotidyl transferases such as the retroviral integrases and the RAG1 subunit of V(D)J recombinase. The RNase-H fold is a mixture of beta sheets and alpha helices with three acidic residues (Asp, Asp, Glu/Asp-DDE/D) that are involved in the metal-mediated cleavage and subsequent integration of DNA. Human THAP9 (hTHAP9), homologous to the well-studied Drosophila P-element transposase (DmTNP), is an active DNA transposase that, although domesticated, still retains the catalytic activity to mobilize transposons.

Background: ChIP (Chromatin immunoprecipitation)-exo has emerged as an important and versatile improvement over conventional ChIP-seq as it reduces the level of noise, maps the transcription factor (TF) binding location in a very precise manner, upto single base-pair resolution, and enables binding mode prediction. Availability of numerous peak-callers for analyzing ChIP-exo reads has motivated the need to assess their performance and report which tool executes reasonably well for the task.

Results: This study has focussed on comparing peak-callers that report direct binding events with those that report indirect binding events.
