Mechanotransduction is the process by which cells detect mechanical forces and convert them into biochemical or electrical signals. This process occurs across various cellular compartments, including the plasma membrane, cytoskeleton, and intracellular organelles. While research has focused mainly on force sensing at the plasma membrane, the mechanisms and significance of intracellular mechanotransduction are just beginning to be understood.

Microcirculation is an essential system that regulates oxygen and nutrients to cells and tissues in response to various environmental stimuli and pathophysiological conditions. Diabetes mellitus can cause microvascular complications including nephropathy, neuropathy, and retinopathy. The pathogenesis of microvascular dysfunction in diabetes is associated with hyperglycemia and the result of an interplay of various factors.

Calcium (Ca)-activated ion channels and lipid scramblases in the transmembrane protein 16 (TMEM16) family are structurally related to mechanosensitive ion channels in the TMEM63 and transmembrane channel-like (TMC) families. Members of this structurally related superfamily share similarities in gating transitions and serve a wide range of physiological functions, which is evident from their disease associations. The TMEM16, TMEM63 and TMC families include members with important functions in the cell membrane and/or intracellular organelles such as the endoplasmic reticulum, membrane contact sites, endosomes and lysosomes.

  • - The study examined how hamstring strain injuries (HSI) and vision affect muscle recruitment and balance in athletes, comparing 14 athletes with HSI to 14 healthy athletes while they performed balance tasks.
  • - Results showed that athletes with HSI had significantly lower activation in their hamstring muscles during balance tasks, leading to increased body sway and reduced stability compared to healthy controls.
  • - The findings suggest that the ongoing muscle activation deficits in athletes with HSI could negatively influence their balance, highlighting the need for targeted balance training in rehabilitation programs.

Background: Obesity and hypercholesterolemia have been associated with better responses to ICIs in NSCLC, while type 2 diabetes (T2D) has been associated with a worse response. However, the association between glucose levels and outcomes remains unknown. This study investigated the impact of mean baseline glucose levels, T2D, dyslipidemia, and obesity on overall survival (OS) in NSCLC patients undergoing ICI therapy.

Research has not demonstrated whether multiple cups of negative pressure cupping therapy would induce interactions of hemodynamic responses between different areas. A multichannel near-infrared spectroscopy (NIRS) was used to assess oxyhemoglobin and deoxyhemoglobin oscillations in response to cupping therapy. Wavelet transform and wavelet phase (WPC) coherence were used to quantify NIRS signals.

  • Immune checkpoint inhibitors (ICIs) significantly improve survival rates for melanoma patients, but the impact of body mass index (BMI) and type 2 diabetes (T2DM) on these outcomes has been unclear.
  • In a study of 2,078 melanoma patients, overweight individuals (BMI≥25 kg/m²) had better median overall survival (71.7 months) compared to non-overweight individuals (36.7 months), while those with T2DM experienced worse survival (28.5 months).
  • The research shows that overweight patients maintained better survival outcomes even after accounting for T2DM, highlighting that being overweight could be advantageous in this context, whereas T2DM negatively affects survival in melanoma patients receiving ICIs.

  • - The study aimed to explore how skin blood flow regulation differs between the upper (forearm) and lower (leg) limbs in healthy adults, marking the first research of its kind using wavelet analysis of blood flow oscillations.
  • - Using laser Doppler flowmetry, researchers measured skin blood flow in 17 participants and analyzed the data to identify the primary controls influencing blood flow, categorized into metabolic, neurogenic, myogenic, respiratory, and cardiac factors.
  • - Findings revealed that skin blood flow was significantly higher in the leg, with metabolic endothelial control being more prominent in the forearm and myogenic control being more prevalent in the leg, highlighting distinct regulatory mechanisms for upper and lower limbs.

  • The study focused on how telehealth-delivered cognitive behavioral therapy for insomnia (tele-CBT-I) affects sleep quality and changes in brain function in fibromyalgia patients who also have insomnia.
  • A total of 35 participants were split into two groups: one receiving tele-CBT-I and the other receiving treatment as usual (TAU), followed by assessments using various standardized scales and brain imaging.
  • Results indicated that tele-CBT-I improved sleep quality more significantly than TAU, altered the functional connectivity in areas related to the salience network, and showed a strong correlation between changes in connectivity and insomnia severity scores.

To facilitate our understanding of proteome dynamics during signaling events, robust workflows affording fast time resolution without confounding factors are essential. We present Surface-exposed protein Labeling using PeroxidaSe, HO, and Tyramide-derivative (SLAPSHOT) to label extracellularly exposed proteins in a rapid, specific, and sensitive manner. Simple and flexible SLAPSHOT utilizes recombinant soluble APEX2 protein applied to cells, thus circumventing the engineering of tools and cells, biological perturbations, and labeling biases.

  • Air insoles can help reduce the risk of diabetic foot ulcers (DFU) by analyzing how different pressures affect foot pressure over time during walking.
  • The study tested three insole pressures (80, 160, and 240 mmHg) and two walking durations (10 and 20 minutes) on 13 healthy participants, showing significant differences in pressure effects.
  • The findings suggest that walking for 10 minutes with an insole pressure of 160 mmHg results in lower pressure values, indicating a reduced risk of DFU compared to higher pressures or longer durations.

Isometric exercise is a non-pharmacologic intervention to improve muscle hemodynamic responses and blood pressure in humans. However, the effects of intensity, duration, and muscle mass factors of isometric exercise on local muscle hemodynamic responses and systemic blood pressure regulation have not been studied. The purpose of this study was to assess whether various modes of isometric exercise could induce various levels of muscle hemodynamic responses that are related to the blood pressure changes.

Objective: This study aims to use the texture analysis of ultrasound images to distinguish the features of microchambers (a superficial thinner layer) and macrochambers (a deep thicker layer) in heel pads between the elderly with and without diabetes, so as to preliminarily explore whether texture analysis can identify the potential injury characteristics of deep tissue under the influence of diabetes before the obvious injury signs can be detected in clinical management.

Methods: Ultrasound images were obtained from the right heel (dominant leg) of eleven elderly people with diabetes (DM group) and eleven elderly people without diabetes (Non-DM group). The TekScan system was used to measure the peak plantar pressure (PPP) of each participant.

  • Bridging exercises are frequently used to help people with low back pain (LBP), but the impact of different contraction modes (isometric vs. dynamic) on low back muscle oxygenation has not been studied.
  • Using near-infrared spectroscopy, researchers measured the hemodynamic responses in the erector spinae muscles of 16 healthy participants during both types of bridging exercises.
  • The findings revealed that dynamic bridging exercises significantly improved muscle oxygenation compared to isometric exercises, indicating that dynamic exercises may be more beneficial for low back muscle health.

: For patients with obstructive jaundice and who are indicated for pancreaticoduodenectomy (PD) or biliary intervention, either endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography and drainage (PTCD) may be indicated preoperatively. However, the possibility of procedure-related postoperative biliary tract infection (BTI) should be a concern. We tried to evaluate the impact of ERCP and PTCD on postoperative BTI.
