Ruvbl1 silencing affects reproduction of the corn planthopper, Peregrinus maidis.

Ruvbl1 (also known as TIP49, Pontin) encodes an ATPase of the AAA+ protein superfamily involved in several cellular functions, including chromatin remodeling, control of transcription, and cellular development (motility, growth, and proliferation). While its role has been well established in model organisms including vertebrates and invertebrates (e.g.

We are what we eat: Implications of host plant suitability on sustainable production of silkworm pupae as novel ingredient with dietary and health benefits.

Although, the impact of mulberry leaves on mortality of Bombyx mori [silkworm] and cocooning rates has been investigated, limited research has exploited the influence on the quality of B. mori pupae. This study evaluated the effects of four mulberry cultivars (Ichinose, Noi-EX-Thailand, Ex-Thika and Victory1) on the nutritional quality of B.

Dynamic changes in medication burden leading to fall and hospital readmissions in older adults: Toward a strategy for improving risk and managing costs.

The majority of a health plan's performance and designated Star Rating is related to medication-related behavior, eg, medication adherence, medication review, and reconciliation, that are intricately related to adverse drug events (ADEs). Altered pharmacodynamics and pharmacokinetics owing to aging make older adults more vulnerable to ADEs like falls, fractures, hospitalizations, and mortality. Prevention of avoidable risk factors such as medication burden can help maintain quality of life.

Isoquinolinequinone N-oxides with diverging mechanisms of action induce collateral sensitivity against multidrug resistant cancer cells.

Multidrug resistance (MDR) is a major challenge in cancer research. Collateral sensitizers, compounds that exploit the enhanced defense mechanisms of MDR cells as weaknesses, are a proposed strategy to overcome MDR. Our previous work reported the synthesis of two novel Isoquinolinequinone (IQQ) N-oxides that induce collateral sensitivity in MDR ABCB1-overexpressing non-small cell lung cancer (NSCLC) and colorectal cancer cells.

Recurrent neurogenic shock as a rare postoperative complication associated with pancreaticoduodenectomy with mesopancreas excision in elderly patient: a case report.

Background: Surgical resection of locally advanced or borderline pancreatic ductal adenocarcinoma is a recognized procedure with curative intent performed in specialized oncology centers. Postoperative dysautonomia such as gastroparesis, mild hypotension, and diarrhea are common in elderly patients undergoing pancreaticoduodenectomy. A distinctive feature of our case, is the severing of an important sympathetic chain by the surgical procedure, leading to recurrent severe neurogenic shock.

Hypoxia as a critical player in extracellular vesicles-mediated intercellular communication between tumor cells and their surrounding microenvironment.

In the past years, increasing attention has been paid to the role of extracellular vesicles (EVs) as mediators of intercellular communication in cancer. These small size particles mediate the intercellular transfer of important bioactive molecules involved in malignant initiation and progression. Hypoxia, or low partial pressure of oxygen, is recognized as a remarkable feature of solid tumors and has been demonstrated to exert a profound impact on tumor prognosis and therapeutic efficacy.

Preclinical studies on the antitumor and non-toxic effect of combining pirfenidone with vinorelbine and carboplatin in non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) shows limited therapeutic response to vinorelbine and carboplatin. Combining these drugs with an antifibrotic drug may enhance their antitumor effect. Pirfenidone is an antifibrotic drug whose antitumor activity has been described in different types of cancer.

Skinny fat model of metabolic syndrome induced by a high-salt/sucrose diet in young male rats.

Childhood and puberty can affect metabolism, leading to tissue injury and malfunction later in life. The consumption of high-processed foods rich in salt and sugar is increasing in middle- and high-income countries, especially among young people. It is necessary to evaluate the effects of high salt and sugar levels in the youth on most injured organs during metabolic challenges.

Our Health Counts Toronto: Commercial tobacco use among Indigenous peoples in Toronto.

Objective: Fueled by the commercial tobacco industry, commercial tobacco use continues to be the leading preventable cause of premature death in Canada, with opportunities to improve health outcomes. The objective of this research was to work with Indigenous partners to generate Indigenous population prevalence estimates of commercial tobacco use in Toronto, and examine the association between smoking and sociodemographic, cultural, resiliency, and social variables.

Methods: Respondent-driven sampling (RDS) was used to generate prevalence estimates of commercial tobacco use and potentially associated sociodemographic, cultural, resiliency, and social connection variables for Indigenous adults living in Toronto.

Darifenacin: a promising chitinase 3-like 1 inhibitor to tackle drug resistance in pancreatic ductal adenocarcinoma.

Purpose: Pancreatic ductal adenocarcinoma (PDAC) is among the most aggressive malignancies. Our previous work revealed Chitinase 3-like 1 (CHI3L1) involvement in PDAC resistance to gemcitabine, identifying it as a promising therapeutic target. Here, we aimed to identify putative CHI3L1 inhibitors and to investigate their chemosensitizing potential in PDAC.

Towards automated inclusion of autoxidation chemistry in models: from precursors to atmospheric implications.

In the last few decades, atmospheric formation of secondary organic aerosols (SOA) has gained increasing attention due to their impact on air quality and climate. However, methods to predict their abundance are mainly empirical and may fail under real atmospheric conditions. In this work, a close-to-mechanistic approach allowing SOA quantification is presented, with a focus on a chain-like chemical reaction called "autoxidation".

Discovery of Potent Isoquinolinequinone -Oxides to Overcome Cancer Multidrug Resistance.

Multidrug resistance (MDR) of human tumors has resulted in an immediate need to develop appropriate new drugs. This work outlines the development of 20 potent IQQ -oxide derivatives in two isomeric families, both exhibiting nanomolar GI against human tumor cell lines. Preliminary NCI-60 tumor screening sees the C(6) isomers achieve a mean GI > 2 times lower than the corresponding C(7) isomers.

P2Y12 Inhibitors Refill Gap Predicts Death in Medicare Beneficiaries on Chronic Dialysis.

Introduction: Oral P2Y inhibitors (P2Y12-I) are commonly used antiplatelet drugs in patients with end-stage kidney disease (ESKD) on chronic dialysis. Although gaps in prescription refills are quite common in patients with ESKD, it remains unclear whether P2Y12-I prescription refill patterns are associated with adverse clinical outcomes.

Methods: We used the United States Renal Data System (USRDS) registry for patients with ESKD to capture new P2Y12-I prescriptions from 2011 to 2015.

GHSR signalling in perinatal phases is involved in liver metabolism at puberty.

Ghrelin has effects that range from the maturation of the central nervous system to the regulation of energy balance. The production of ghrelin increases significantly during the first weeks of life. Studies have addressed the metabolic effects of liver-expressed antimicrobial peptide 2 (LEAP2) in inhibiting the effects evoked by ghrelin, mainly in glucose homeostasis, insulin resistance, and lipid metabolism.

Early Methylglyoxal Exposure Leads to Worsened Cardiovascular Function in Young Rats.

Background: Though maternal diabetes effects are well described in the literature, the effects of maternal diabetes in postnatal phases are often overlooked. Diabetic individuals have higher levels of circulating glycotoxins, and there is a positive correlation between maternal-derived glycotoxins and circulating glycotoxins in their progeny. Previous studies evaluated the metabolic effects of high glycotoxin exposure during lactation in adult animals.

Detection dogs fighting transnational narcotraffic: performance and challenges under real customs scenario in Brazil.

Narcotic Detection Dogs (NDDs) are essential tools in the fight against drug trafficking, acting with high precision and improving efficiency at border posts. When trained efficiently, these dogs can detect a great variety of compounds, such as cocaine, marijuana and its derivatives, and synthetic drugs, among others. Most of the knowledge on canine detection processes and efficiency has been determined in experimentally controlled conditions, but narcotic seizures detected by dogs in realistic anti-drug operations have not yet been critically determined in a Country with continental dimensions such as Brazil.

Three-dimensional imaging to estimate in vivo body and carcass chemical composition of growing beef-on-dairy crossbred bulls.

The dynamics of cattle body chemical composition during growth and fattening periods determine animal performance and beef carcass quality. The aim of this study was to estimate the empty body (EB) and carcass chemical composition of growing beef-on-dairy crossbred bulls (Brown Swiss breed as dam with Angus, Limousin or Simmental as sire) using three-dimensional (3D) imaging. The 3D images of the cattle's external body shape were recorded in vivo on 48 bulls along growth trajectory (75-520 kg BW and 34-306 kg hot carcass weight [HCW]; set 1) and on 70 bulls at target market slaughter weight, including 18 animals from set 1 (average 517 ± 10 kg BW and 289 ± 10 kg HCW; set 2).

Sodium overload during postnatal phases impairs diastolic function and exacerbates reperfusion arrhythmias in adult rats.

Sodium overload during childhood impairs baroreflex sensitivity and increases arterial blood pressure and heart rate in adulthood; these effects persist even after high-salt diet (HSD) withdrawal. However, the literature lacks details on the effects of HSD during postnatal phases on cardiac ischemia/reperfusion responses in adulthood. The current study aimed to elucidate the impact of HSD during infancy adolescence on isolated heart function and cardiac ischemia/reperfusion responses in adulthood.
