Developmental basis of natural tooth shape variation in cichlid fishes.

While most dentate non-mammalian vertebrates possess simple conical teeth, some demonstrate complex tooth shapes. Lake Malawi cichlid fishes are an extreme example of this, exhibiting a myriad of tooth shapes driven by an ecologically derived rapid evolution of closely related but distinct species. Tooth shape in mammals is generally considered to be established by signaling centers called primary and secondary enamel knots, which are not believed to be present in non-mammalian vertebrates.

Increased plugging latency in cycling epiERα-/- (Esr1f/-Wnt7aCre/+) mice.

Wnt7a-Cre is a commonly used for generating uterine epithelial conditional knockout mice, such as epiERα-/- (Esr1f/-Wnt7aCre/+) and epiPR-/- (Pgrf/-Wnt7aCre/+). We noticed that epiERα-/- females, but not epiPR-/- females, have prolonged plugging latency, which is the duration between continuous cohabitation and detection of the first vaginal plug (a sign of mating). Mating occurs in proestrus and/or estrus stages of the estrous cycle.

Operation of spinal sensorimotor circuits controlling phase durations during tied-belt and split-belt locomotion after a lateral thoracic hemisection.

Locomotion is controlled by spinal circuits that interact with supraspinal drives and sensory feedback from the limbs. These sensorimotor interactions are disrupted following spinal cord injury. The thoracic lateral hemisection represents an experimental model of an incomplete spinal cord injury, where connections between the brain and spinal cord are abolished on one side of the cord.

"It's Like You're Feeding Your Child Twice": Barriers and Facilitators to Human Milk Feeding Children With Cystic Fibrosis.

Background: Cystic Fibrosis Foundation guidelines recommend human milk (HM) as the ideal source of nutrition for children with CF (cwCF). Despite known pulmonary and nutritional benefits, fewer cwCF ever receive HM compared to the general population. Early nutrition choices are preference-sensitive, yet little is known about the factors that impede or sustain HM feeding among parents of cwCF.

Pharmacological Dissection Identifies Retatrutide Overcomes the Therapeutic Barrier of Obese TNBC Treatments through Suppressing the Interplay between Glycosylation and Ubiquitylation of YAP.

Triple-negative breast cancer (TNBC) in obese patients remains challenging. Recent studies have linked obesity to an increased risk of TNBC and malignancies. Through multiomic analysis and experimental validation, a dysfunctional Eukaryotic Translation Initiation Factor 3 Subunit H (EIF3H)/Yes-associated protein (YAP) proteolytic axis is identified as a pivotal junction mediating the interplay between cancer-associated adipocytes and the response to anti-cancer drugs in TNBC.

Comorbidities and Healthcare Utilization Among Young Adults With Congenital Heart Defects by Down Syndrome Status-Congenital Heart Survey to Recognize Outcomes, Needs, and wellbeinG, 2016-2019.

Background: Almost half of individuals born with Down syndrome (DS) have congenital heart defects (CHDs). Yet, little is known about the health and healthcare needs of adults with CHDs and DS. Therefore, we examined comorbidities and healthcare utilization of this population.

Increasing trends of cannabinoid hyperemesis syndrome in youth: The grass is not always greener.

This study investigated trends in suspected cannabinoid hyperemesis syndrome (CHS)-related emergency department visits among youth (15-24 years old) in the United States between 2006 and 2020. Using data from the Nationwide Emergency Room Sample, over 55,000 suspected CHS-related visits were identified, with an average annual increase of 28.1% per year.

Comparing the effects of verbenone, methyl salicylate, and permethrin on attacks of ambrosia beetles (Coleoptera: Curculionidae Scolytinae) in ornamental nurseries.

The granulate ambrosia beetle, Xylosandrus crassiusculus (Motschulsky), and the black stem borer, Xylosandrus germanus (Blandford) are important pests in ornamental nurseries in the eastern USA. These beetles are managed mainly using preventative trunk applications of pyrethroids, such as permethrin or bifenthrin when females typically fly out of woodlots and attack young trees in the spring. Verbenone and methyl salicylate are potential phytochemicals reported as repellants but not completely validated in ornamental nurseries for ambrosia beetle management as an alternative option.

Stabilization of [(N)BX] and [(N)BX] (X = H, F, Cl, Br) by Conjugation and Hyperconjugation Effects.

The isolation of nucleophilic boron bases has led to a paradigm shift in boron chemistry. Previous studies of the bis(carbene) borylene complexes revealed that these compounds possess strong donor abilities, and their reaction inertness is due to the large steric hindrance between boron reagents and reactant. In the present study, we have theoretically studied the [(N)BX] and [(N)BX] compounds (X = H, F, Cl, Br).

Verticillin A-Loaded Surgical Buttresses Prevent Local Pancreatic Cancer Recurrence in a Murine Model.

The fungal metabolite verticillin A is a potent and selective histone methyltransferase inhibitor. It regulates apoptosis, the cell cycle, and stress response, and displays potent activity in the suppression of tumor cell growth in several different in vivo models. Verticillin A sensitizes pancreatic cancer cells to anti-PD-1 immunotherapy by regulating PD-L1 expression.

Secreted small RNAs of are biomarkers for diagnosis of primary amoebic meningoencephalitis.

Rapid and accurate diagnostics are needed to effectively detect and treat primary amoebic meningoencephalitis (PAM) caused by (). Delayed diagnosis and similarities to other causes of meningitis contribute to a case mortality rate of >97%. Thus, there is an unmet medical need for a non-invasive liquid biopsy diagnostic method.

Enforced E-selectin ligand installation enhances homing and efficacy of adoptively transferred T cells.

Adoptive T-cell transfer has revolutionized the treatment of hematological malignancies. However, this approach has had very limited success in treating solid tumors, largely due to inadequate infiltration of vascularly administered T cells at tumor sites. The shear-resistant interaction between endothelial E-selectin and its cognate ligand expressed on leukocytes, sialyl Lewis X (sLe), is an essential prerequisite for extravasation of circulating leukocytes.

The PIKASO trial (Preventing Injured Knees from Osteoarthritis: Severity Outcomes): Rationale and design features for a randomized controlled trial.

Objective: Given the high burden and increasing prevalence of post-traumatic osteoarthritis (PTOA), identifying clinically beneficial strategies to prevent or delay its onset could improve the quality of life of those at high risk of developing the disease.

Methods: Preventing Injured Knees from OsteoArthritis: Severity Outcomes (PIKASO) is a multicenter blinded, parallel, two-arm randomized controlled trial of 512 individuals aged 18-45 years undergoing anterior cruciate ligament reconstruction (ACLR). This study is designed to evaluate the efficacy of a 12-month intervention of oral metformin vs.

Variations in the Terminal Branches of the Brachial Plexus in the Axillary Fossa.

The brachial plexus is the primary nerve source for the upper limb. Variations in its anatomy can alter the nerve supply to the upper extremity. Such deviations are clinically important, as they can change the symptomatology of various pathologic conditions, leading to misdiagnosis, inadequate treatment, and surgical failures as a consequence.

Knee Ligament Injuries in the National Football League: Impact of Field Surface Type During the 2020-2023 Seasons.

Introduction A subject of ongoing debate within the National Football League (NFL) community revolves around the comparative risk of anterior cruciate ligament (ACL) injuries on natural versus artificial turf field surfaces. There have been mixed results as to whether there is a difference in injury rates depending on the playing surface and what factors might play a role in affecting these rates. Methods This study aims to compare the incidence of in-game knee ligament tears in the NFL during the 2020-2023 seasons.

Characterization of Pancreatic Collagen-Expressing Fibroblasts in Mouse Acute Pancreatitis.

Background And Aims: Pancreatic stellate cells (PSCs) are critical mediators in chronic pancreatitis with an undefined role in acute pancreatitis (AP). PSCs consist of a heterogenous group of cells and are considered interchangeable with pancreatic fibroblasts. This study explored the heterogeneous nature of PSCs by characterizing pancreatic collagen-expressing fibroblasts (PCFs) via lineage tracing in mouse normal and AP pancreas and determining the effect of PCF depletion in AP.

Neighborhood Socioeconomic Disadvantage and Physical Disorder, Parenting Strategies, and Youths' Future Orientation.

Neighborhood disadvantage has been linked to youths' diminished future orientation, defined as the degree to which one thinks about, anticipates, and plans for the future. Yet, parenting behaviors may moderate this link. Using longitudinal data from parent-child dyads ( = 101, 51.

Sleep duration, sleep disturbances and skeletal muscle mass change over time: A population-based longitudinal analysis in Peru.

Background: The skeletal muscle has mainly a structural function and plays a role in human's metabolism. Besides, the association between sleep quality and muscle mass, in the form of sarcopenia, has been reported. This study aimed to assess whether changes of skeletal muscle mass (SMM) over time are associated with baseline sleep duration and disturbances in a resource-constrained adult Peruvian population.

Measuring Realistic Emotional Perception With EEG: A Comparison of Multimodal Videos and Naturalistic Scenes.

Emotional experiences involve dynamic multisensory perception, yet most EEG research uses unimodal stimuli such as naturalistic scene photographs. Recent research suggests that realistic emotional videos reliably reduce the amplitude of a steady-state visual evoked potential (ssVEP) elicited by a flickering border. Here, we examine the extent to which this video-ssVEP measure compares with the well-established Late Positive Potential (LPP) that is reliably larger for emotional relative to neutral scenes.

Canine cystic astrocytomas: 7 cases.

Tumoral macrocysts (grossly observable cysts) are common in human pilocytic astrocytomas but are rarely reported in canine astrocytomas. Here we describe 7 canine astrocytomas with macrocysts. The median age of affected patients was 9.

Meningioma in the fourth ventricle in 2 cats.

Feline meningiomas typically arise on the surface of the brain but can occur in the third ventricle. Meningiomas in the fourth ventricle have not been reported in cats, to our knowledge. Here, we describe the clinical and pathologic findings of meningioma in the fourth ventricle in 2 cats.

Aspergillosis in 41 wild bird species in the eastern United States: a 22-year retrospective review.

Aspergillosis is the most commonly and widely reported fungal infection in birds. Disease development is often secondary to stressors that cause immunocompromise, and it is typically regarded as a disease of captivity. We retrospectively evaluated data from 133 birds diagnosed with aspergillosis at the Southeastern Cooperative Wildlife Disease Study from 2001-2023 to assess diversity and relative frequency across avian taxa, gross and histologic lesion patterns, and comorbidities.

Intergenerational impacts of racial discrimination on child executive functioning problems.

The proposed study sought to investigate whether maternal experiences of racial discrimination and gendered racial stress are associated with offspring executive functioning. Total 266 Black mother-child pairs in the United States were assessed from pregnancy through child age of 4 years. We hypothesized that children whose mothers reported higher rates of perceived gendered racial stress during pregnancy and racial discrimination throughout their lifetime would have lower scores on executive functioning assessments.
