Improved Mass Spectrometry-Based Methods Reveal Abundant Propionylation and Tissue-Specific Histone Propionylation Profiles.

Histone posttranslational modifications (PTMs) have crucial roles in a multitude of cellular processes, and their aberrant levels have been linked with numerous diseases, including cancer. Although histone PTM investigations have focused so far on methylations and acetylations, alternative long-chain acylations emerged as new dimension, as they are linked to cellular metabolic states and affect gene expression through mechanisms distinct from those regulated by acetylation. Mass spectrometry is the most powerful, comprehensive, and unbiased method to study histone PTMs.

Caloric restriction leads to druggable LSD1-dependent cancer stem cells expansion.

Caloric Restriction (CR) has established anti-cancer effects, but its clinical relevance and molecular mechanism remain largely undefined. Here, we investigate CR's impact on several mouse models of Acute Myeloid Leukemias, including Acute Promyelocytic Leukemia, a subtype strongly affected by obesity. After an initial marked anti-tumor effect, lethal disease invariably re-emerges.

Inhibition of the lysine demethylase LSD1 modulates the balance between inflammatory and antiviral responses against coronaviruses.

Innate immune responses to coronavirus infections are highly cell specific. Tissue-resident macrophages, which are infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients but are inconsistently infected in vitro, exert critical but conflicting effects by secreting both antiviral type I interferons (IFNs) and tissue-damaging inflammatory cytokines. Steroids, the only class of host-targeting drugs approved for the treatment of coronavirus disease 2019 (COVID-19), indiscriminately suppress both responses, possibly impairing viral clearance.

Lymph Node Metastasis and Patterns of Recurrence in Vulvar Carcinoma: 10 Years' Single Center Experience.

Vulvar carcinoma is a relatively rare malignancy and there is a paucity of data, especially from India and other developing countries regarding the prognostic factors impacting recurrence and survival. A retrospective observational study was conducted in the Department of Gynecologic Oncology at a tertiary care, regional cancer institute, including all patients with carcinoma vulva who underwent surgery between 2009 and 2018. Demographic profile, surgical-pathological information, details of neo-adjuvant chemotherapy, adjuvant radiation and chemotherapy, and peri-operative complications were analyzed.

Impact of Facemasks Use on Interpersonal Communication in a Clinical Setup: A Questionnaire Based Study.

Precautionary measures such as physical distancing, wearing a mask, and hand hygiene to suppress virus transmission necessitated a shift in the communication paradigm.The study aimed to check the effects of wearing masks (N95, surgical, and cloth) due to the COVID-19 pandemic on interpersonal communication in audiology-speech-language pathology clinical setup from a clinician perspective. A total of 105 participants, 17 males, and 88 females, in the age range of 19 to 29 years (Mean age = 21.
