Activation of connexin hemichannels enhances mechanosensitivity and anabolism in disused and aged bone.

Mechanical loading, essential for bone health, promotes bone formation and remodeling. However, the positive response diminishes in cases of disuse and aging, leading to bone loss and an increased fracture risk. This study demonstrates that activating hemichannels (HCs) using a connexin 43 (Cx43) antibody, Cx43(M2), in bone osteocytes revitalizes aging and disused bones.

The Laws of Attraction: Chemokines as Critical Mediators in Cancer Progression and Immunotherapy Response in Bladder Cancer.

Bladder cancer (BCa) is a prevalent urogenital malignancy, characterized by a myriad of genetic and environmental risk factors that drive its progression. Approximately 75% of bladder tumors are non-muscle-invasive at diagnosis. For such cases, bladder preservation is often feasible with intravesical chemotherapy or immunotherapy.

Intra-abdominal nocardiosis and scedosporiosis in a dog: case report and literature review.

A 2-y-old, intact female, mixed-breed dog was presented to the veterinary hospital with abdominal distension, anemia, and lethargy following a chronic history of nonspecific gastrointestinal signs. CBC and serum biochemistry revealed moderate nonregenerative anemia with neutrophilia, hypoalbuminemia, hyperglobulinemia, hypoglycemia, decreased urea and creatinine, and hypercholesterolemia. Abdominal radiographs and ultrasound revealed a large heterogeneous mesenteric mass and ascites.

Serum metabolomics analysis of malnutrition in patients with gastric cancer: a cross sectional study.

Background: Although malnutrition is common in cancer patients, its molecular mechanisms has not been fully clarified. This study aims to identify significantly differential metabolites, match the corresponding metabolic pathways, and develop a predictive model of malnutrition in patients with gastric cancer.

Methods: In this cross-sectional study, we applied non-targeted metabolomics using liquid chromatography-mass spectrometry to explore the serum fingerprinting of malnutrition in patients with gastric cancer.

Degenerative and regenerative peripheral processes are associated with persistent painful chemotherapy-induced neuropathies in males and females.

This study investigated the time course of gene expression changes during the progression of persistent painful neuropathy caused by paclitaxel (PTX) in male and female mouse hindpaws and dorsal root ganglia (DRG). Bulk RNA-seq was used to examine these gene expression changes at 1, 16, and 31 days post-last PTX. At these time points, differentially expressed genes (DEGs) were predominantly related to the reduction or increase in epithelial, skin, bone, and muscle development and to angiogenesis, myelination, axonogenesis, and neurogenesis.

Associations of tissue damage induced inflammatory plasticity in masseter muscle with the resolution of chronic myalgia.

Gene plasticity during myogenous temporomandibular disorder (TMDM) development is largely unknown. TMDM could be modeled by intramuscular inflammation or tissue damage. To model inflammation induced TMDM we injected complete Freund's adjuvant (CFA) into masseter muscle (MM).

Transcriptional profiles of non-neuronal and immune cells in mouse trigeminal ganglia.

Non-neuronal cells constitute 90%-95% of sensory ganglia. These cells, especially glial and immune cells, play critical roles in the modulation of sensory neurons. This study aimed to identify, profile, and summarize the types of trigeminal ganglion (TG) non-neuronal cells in naïve male mice using published and our own data generated by single-cell RNA sequencing, flow cytometry, and immunohistochemistry.

Antibody-drug conjugates: the paradigm shifts in the targeted cancer therapy.

Cancer is one of the deadliest diseases, causing million of deaths each year globally. Conventional anti-cancer therapies are non-targeted and have systemic toxicities limiting their versatile applications in many cancers. So, there is an unmet need for more specific therapeutic options that will be effective as well as free from toxicities.

Multifocal hepatocellular carcinoma: a narrative review assessing treatment options from the interventional radiologist's perspective.

Background And Objective: It is estimated that 35-40% of hepatocellular carcinoma (HCC) patients present with multiple nodules at the time of diagnosis. Treating multifocal disease is difficult given patient population heterogeneity. Multiple interventional radiological (IR) options, including ablation, transarterial chemoembolization (TACE), and transarterial radioembolization (TARE), are available, each with its own merits and limitations.

Update on the genetics of paragangliomas.

Paragangliomas (PGL) of the adrenal (also known as pheochromocytomas) or extra-adrenal neural crest-derived cells are highly heritable tumors, usually driven by single pathogenic variants that occur mutually exclusively in genes involved in multiple cellular processes, including the response to hypoxia, MAPK/ERK signaling, and WNT signaling. The discovery of driver mutations has led to active clinical surveillance with outcome implications in familial PGL. The spectrum of mutations continues to grow and reveal unique mechanisms of tumorigenesis that inform tumor biology and provide the rationale for targeted therapy.

Role, race, and place: Prostate cancer disparities in Patients' and Partners' health outcomes and psychosocial factors.

Purpose: This study aimed to examine the effects of participant role (patient vs. partner), race (white vs. non-white), and place (less vs.

Health behaviors, obesity, and marital status among cancer survivors: a MEPS study.

Purpose: Promoting positive health behaviors helps improve cancer survivors' health outcomes during survivorship; however, little is known about whether health behaviors differ by marital status. The purpose is to examine whether health behaviors and obesity among cancer survivors vary by marital status and whether the type of cancer and sociodemographic factors influence the relationship.

Methods: We examined smoking, physical activity, and body mass index (BMI) among 1880 individuals diagnosed with prostate, breast, or colon cancer who were identified from the 2011-2017 Medical Expenditure Panel Survey (MEPS).

Sex-dependent pain trajectories induced by prolactin require an inflammatory response for pain resolution.

Pain development and resolution patterns in many diseases are sex-dependent. This study aimed to develop pain models with sex-dependent resolution trajectories, and identify factors linked to resolution of pain in females and males. Using different intra-plantar (i.

Pituitary hormones are specifically expressed in trigeminal sensory neurons and contribute to pain responses in the trigeminal system.

Trigeminal (TG), dorsal root (DRG), and nodose/jugular (NG/JG) ganglia each possess specialized and distinct functions. We used RNA sequencing of two-cycle sorted Pirt-positive neurons to identify genes exclusively expressing in L3-L5 DRG, T10-L1 DRG, NG/JG, and TG mouse ganglion neurons. Transcription factor Phox2b and Efcab6 are specifically expressed in NG/JG while Hoxa7 is exclusively present in both T10-L1 and L3-L5 DRG neurons.

Background: Undocumented immigration is often accompanied by multiple and complex stressors, which over time may increase the risk for chronic pain.

Objective: This study aimed to identify the prevalence of chronic pain and its association with psychological distress among undocumented Latinx immigrants in the USA.

Design/participants: We used respondent-driven sampling to collect and analyze data from clinical interviews with 254 undocumented Latinx immigrants, enabling inference to a population of 22,000.

Umbilical Reconstruction Techniques: A Literature Review.

Background: There are many instances in which sacrificing the umbilicus is unavoidable. Umbilical reconstruction (umbiliconeoplasty) is an important surgical procedure to complete the abdomen's reconstruction and to give again a pleasant cosmetic appearance.

Objectives: To provide a complete overview of all surgical techniques for umbiliconeoplasty described in the literature.

Transcriptomic sex differences in sensory neuronal populations of mice.

Many chronic pain conditions show sex differences in their epidemiology. This could be attributed to sex-dependent differential expression of genes (DEGs) involved in nociceptive pathways, including sensory neurons. This study aimed to identify sex-dependent DEGs in estrous female versus male sensory neurons, which were prepared by using different approaches and ganglion types.

Regulation of cancer cell glucose metabolism is determinant for cancer cell fate after melatonin administration.

Several oncogenic pathways plus local microenvironmental conditions, such as hypoxia, converge on the regulation of cancer cells metabolism. The major metabolic alteration consists of a shift from oxidative phosphorylation as the major glucose consumer to aerobic glycolysis, although most of cancer cells utilize both pathways to a greater or lesser extent. Aerobic glycolysis, together with the directly related metabolic pathways such as the tricarboxylic acid cycle, the pentose phosphate pathway, or gluconeogenesis are currently considered as therapeutic targets in cancer research.

"Abrazame Que Ayuda" (Hug Me, It Helps): Social Support and the Effect of Perceived Discrimination on Depression among US- and Foreign-Born Latinxs in the USA.

Background: Higher level of social support is known to mitigate the effect of ethnic discrimination on depression symptoms, yet little is known as to which type of social support may be most effective for ameliorating the negative health effects of perceived ethnic discrimination among Latinxs varying in nativity status. The purpose of this study is to examine the association between perceived ethnic discrimination and depression among US- and foreign-born Latinxs, and to identify specific types of social support that may buffer the aforementioned association in this population.

Methods: Data from 1340 Latinx respondents (70% US-born; 30% foreign-born) collected from the Texas City Stress and Health Study (TCSHS) was used in this study.

The tumor suppressor TMEM127 regulates insulin sensitivity in a tissue-specific manner.

Understanding the molecular components of insulin signaling is relevant to effectively manage insulin resistance. We investigated the phenotype of the TMEM127 tumor suppressor gene deficiency in vivo. Whole-body Tmem127 knockout mice have decreased adiposity and maintain insulin sensitivity, low hepatic fat deposition and peripheral glucose clearance after a high-fat diet.

Intrapleural Impedance Sensor Real-Time Tracking of Pneumothorax in a Porcine Model of Air Leak.

In patients with alveolar-to-pleural air leak due to recent surgery or trauma, clinicians tend to manage chest tubes with suction therapy. Nonsuction therapy is associated with shorter chest tube duration but also a higher risk of pneumothorax. We sought to develop an intrapleural electrical impedance sensor for continuous, real-time monitoring of pneumothorax development in a porcine model of air leak as a means of promoting nonsuction therapy.
