Background: The Canalith Repositioning Maneuver (CRM) is often ineffective for persistent geotropic direction-changing positional nystagmus (DCPN). In these cases, determining the lesion side can be challenging, as the null plane side and the side with stronger nystagmus on the roll test are frequently opposite.

Objectives: This study investigates whether the low therapeutic efficacy of CRM in persistent DCPN could be attributed to incorrect determination of the lesion side.

The gonadotropin-releasing hormone (GnRH) neurons represent the key output cells of the neural network controlling mammalian fertility. We used GCaMP fiber photometry to record the population activity of the GnRH neuron distal projections in the ventral arcuate nucleus where they merge before entering the median eminence to release GnRH into the portal vasculature. Recordings in freely behaving intact male and female mice revealed abrupt ~8 min duration increases in activity that correlated perfectly with the appearance of a subsequent pulse of luteinizing hormone (LH).

Introduction: The early diagnosis and appropriate treatment of monogenic glomerular diseases can reduce kidney failure, avoid unnecessary investigations such as kidney biopsies and ineffective treatment with immunosuppressants, guide transplant decisions, and inform the genetic risks of their family members. Yet, genetic testing for kidney disease is underutilized in Singapore. We aimed to implement a nephrologist-led genetic service and evaluate the acceptance, adoption, utility, and cost-effectiveness of genetic testing for monogenic glomerular disease in Singapore.

Cancer is a multifaceted disease influenced by various mechanisms, including the generation of reactive oxygen species (ROS), which have a paradoxical role in both promoting cancer progression and serving as targets for therapeutic interventions. At low concentrations, ROS serve as signaling agents that enhance cancer cell proliferation, migration, and resistance to drugs. However, at elevated levels, ROS induce oxidative stress, causing damage to biomolecules and leading to cell death.

Background/objectives: When the facial nerve is severed and a nerve graft is required, motor nerves are typically connected in the forward direction, while sensory nerves are connected in the reverse direction. However, there is limited research on the effects of reversing this connection, and no studies have been conducted using the same facial nerve. This study aimed to investigate the effects of forward and reverse suturing on nerve regeneration following facial nerve axotomy.

Introduction: Optimal adherence to recommended diets is crucial to achieving long-term glycaemic control among individuals with type 2 diabetes (T2D) individuals. However, there is limited evidence on the effectiveness of interventions that target dietary adherence through social networks. Since social networks can influence individuals' health behaviours, it is important to thoroughly evaluate the impact of social network interventions on dietary adherence in adults with T2D.

Article Synopsis
  • - The study examined the diagnosis and management of cancer of unknown primary (CUP) in Canada from 2012 to 2021, noting an increase in both 5-year survival rates and identification of primary tumor sites over the decade.
  • - Researchers found that while advanced diagnostic tests helped identify primary tumor sites, this identification did not improve overall survival; instead, patients with specific "favorable subtypes" saw significantly better outcomes.
  • - The findings suggest that focusing on discovering and understanding these favorable subtypes may be more beneficial for improving survival rates in CUP patients, rather than solely trying to find the primary tumor site.

The gonadotropin-releasing hormone (GnRH) neurons operate as a neuronal ensemble exhibiting coordinated activity once every reproductive cycle to generate the preovulatory GnRH surge. Using GCaMP fiber photometry at the GnRH neuron distal dendrons to measure the output of this widely scattered population in female mice, we find that the onset, amplitude, and profile of GnRH neuron surge activity exhibits substantial variability from cycle to cycle both between and within individual mice. This was also evident when measuring successive proestrous luteinizing hormone surges.
