Exploring the Connection: Moyamoya Disease and Its Implications for Cardiovascular Health.

Moyamoya disease (MMD) is a vascular disorder characterized by steno-occlusive alterations in cerebral arteries, often resulting in ischemic or hemorrhagic events predominantly affecting the female population and more common in Asian populations. Despite its predominantly neurological manifestations, recent research suggests a potential association between MMD and cardiovascular diseases (CVDs). MMD involves various genetic and environmental factors, with mutations in the RNF213 gene being strongly implicated in disease susceptibility, with histopathological findings revealing intimal lesions and smooth muscle proliferation, contributing to vascular occlusion as well as dysregulation of circulating endothelial and smooth muscle progenitor cells further complicating MMD's pathogenesis.

A Rare Case of Bladder Melanosis: A Case Report and Review of the Literature.

Bladder melanosis is a rare and poorly understood condition involving melanin pigmentation within the urothelial mucosa. Cases often present with haematuria, urinary obstructive symptoms, or cystitis. While generally considered benign, its potential association with malignancy warrants regular monitoring, as cases have previously been reported of an association with urothelial carcinoma and melanoma, although it is unclear whether there is a causal relationship.

Longitudinal imaging of the taste bud in vivo with two-photon laser scanning microscopy.

Taste bud cells in the tongue transduce taste information from chemicals in food and transmit this information to gustatory neurons in the geniculate ganglion that innervate taste buds. The peripheral taste system is a dynamic environment where taste bud cells are continuously replaced, but further understanding of this phenomenon has been limited by the inability to directly observe this process. To overcome this challenge, we combined chronic in vivo two-photon laser scanning microscopy with genetic labeling of gustatory neurons and taste buds to observe how cells within the taste bud change over time.

Stress disrupts engram ensembles in lateral amygdala to generalize threat memory in mice.

Stress induces aversive memory overgeneralization, a hallmark of many psychiatric disorders. Memories are encoded by a sparse ensemble of neurons active during an event (an engram ensemble). We examined the molecular and circuit processes mediating stress-induced threat memory overgeneralization in mice.

Evaluation of preoperative intraperitoneal injection of bupivacaine for intraoperative antinociception in cats undergoing ovariohysterectomy: A randomized clinical trial.

Objective: To determine if preoperative intraperitoneal bupivacaine can minimize intra- and postoperative nociception/pain in cats undergoing ovariohysterectomy.

Study Design: Prospective, randomized, investigator-blinded, placebo-controlled clinical trial.

Animals: Forty-seven, intact female cats.

Pediatric Human Papillomavirus Vaccination Rates Within a Tertiary Military Medical Center.

Objective: To determine our center's human papillomavirus (HPV) vaccination rate and identify common negative perceptions surrounding the vaccine to guide more effective HPV vaccine counseling.

Methods: We reviewed immunization records for patients ages 11 to 26 that receive care at Brooke Army Medical Center. Vaccine uptake rate was determined by dividing the number of patients who had completed the HPV vaccine series by the total target population.

Evaluation of preoperative rectus sheath block with bupivacaine for analgesia in cats undergoing ovariohysterectomy: a cadaveric and randomized clinical study.

Objective: Phase 1: to determine the feasibility of desensitizing ventral branches of spinal nerves within the rectus sheath using an ultrasound-guided rectus sheath block (USRSB). Phase 2: to determine the effect of preoperative USRSB on intraoperative responses to surgical stimulation and postoperative pain.

Study Design: Cadaveric study and prospective, randomized, blinded, parallel-arm clinical trial.

PCP auto count: a novel Fiji/ImageJ plug-in for automated quantification of planar cell polarity and cell counting.

During development, planes of cells give rise to complex tissues and organs. The proper functioning of these tissues is critically dependent on proper inter- and intra-cellular spatial orientation, a feature known as planar cell polarity (PCP). To study the genetic and environmental factors affecting planar cell polarity, investigators must often manually measure cell orientations, which is a time-consuming endeavor.

Differential posttraumatic stress disorder symptom cluster response to stellate ganglion block: secondary analysis of a randomized controlled trial.

Empirically supported treatments for posttraumatic stress disorder (PTSD) exist, but research suggests these therapies are less effective, acceptable, and feasible to deliver to active duty service members (SMs) compared to civilians. Stellate ganglion block (SGB) procedure, in which a local anesthetic is injected around the cervical sympathetic chain or stellate ganglion to temporarily inhibit sympathetic nervous activity, is gaining popularity as an alternative PTSD treatment in military settings. However, it is unknown whether certain PTSD symptoms are more responsive to SGB than others.

: A Rare but Important Mutation.

We report the case of a 7-year-old boy who presented with post-viral myositis, rhabdomyolysis, and hepatitis, who was later readmitted due to a seizure-like activity and ultimately found to have episodes of recalcitrant polymorphic ventricular tachycardia secondary to simultaneous QT prolongation and severe hypothyroidism. Temporary transvenous atrial pacing was successful at controlling the ventricular arrhythmias in the intensive care unit. With levothyroxine therapy and cessation of QT-prolonging medications, the corrected QT (QTc) normalized.

HPK1 citron homology domain regulates phosphorylation of SLP76 and modulates kinase domain interaction dynamics.

Hematopoietic progenitor kinase 1 (HPK1) is a negative regulator of T-cell receptor signaling and as such is an attractive target for cancer immunotherapy. Although the role of the HPK1 kinase domain (KD) has been extensively characterized, the function of its citron homology domain (CHD) remains elusive. Through a combination of structural, biochemical, and mechanistic studies, we characterize the structure-function of CHD in relationship to KD.

Large-scale annotated dataset for cochlear hair cell detection and classification.

Our sense of hearing is mediated by cochlear hair cells, of which there are two types organized in one row of inner hair cells and three rows of outer hair cells. Each cochlea contains 5-15 thousand terminally differentiated hair cells, and their survival is essential for hearing as they do not regenerate after insult. It is often desirable in hearing research to quantify the number of hair cells within cochlear samples, in both pathological conditions, and in response to treatment.

Preclinical validation of NeoWarm, a low-cost infant warmer and carrier device, to ameliorate induced hypothermia in newborn piglets as models for human neonates.

Introduction: Approximately 1.5 million neonatal deaths occur among premature and small (low birthweight or small-for gestational age) neonates annually, with a disproportionate amount of this mortality occurring in low- and middle-income countries (LMICs). Hypothermia, the inability of newborns to regulate their body temperature, is common among prematurely born and small babies, and often underlies high rates of mortality in this population.

The transcription factor is essential for the survival of postnatal and adult mouse cochlear hair cells and normal hearing.

Introduction: Hair cells (HCs) of the cochlea are responsible for sound transduction and hearing perception in mammals. Genetic mutations in the transcription factor cause non-syndromic autosomal dominant hearing loss in humans (DFNA15) which varies in the age of onset depending on the individual mutation. Mouse models with germline deletion or mutations in have previously demonstrated its critical role in the maturation and survival of cochlear HCs during embryonic development.
