Immediate effects of manual therapy on respiratory functions in healthy young individuals: a randomized controlled trial.

This study aimed to investigate the immediate effects of manual therapy (MT) on the respiratory functions of healthy young individuals. The study included 104 participants, consisting of university students (87 females, 17 males, mean age 20.1 ± 2.2). Participants were randomly assigned to the MT (experimental; n = 52) and sham-MT (control; n = 52) groups. The experimental group underwent thoracic manipulations and mobilizations along with diaphragm mobilization. In the control group, the hands were placed on the same regions, but no specific intervention was applied. All participants underwent respiratory function testing before and after the intervention using a portable spirometer (PEF- Peak expiratory flow; FEV 1- Forced expiratory volume in 1 s; FVC- Forced vital capacity and FEV1/FVC- Tiffeneau index). In the experimental group, there was a significant increase in the mean PEF value following MT application from 296.3 ± 110.8 to 316.1 ± 119.1 (p = 0.018). Conversely, the mean PEF value in the control group showed a slight decrease from 337.1 ± 93.3 to 324.5 ± 89.2 (p = 0.002). No significant changes were observed in FVC, FEV1, or FEV1/FVC values pre- and post-intervention in either groups. A single MT session led to a significant improvement in PEF in healthy young individuals. Further research is needed to explore the long-term effects of MT on respiratory functions and its potential implications in clinical practice.Trial registration ClinicalTrials.gov: NCT05934240 (06/07/2023).

Serum adiponectin and peroxisome proliferator-activated receptors-γ levels in obese patients with and without prediabetes.

OBJECTIVE: Obesity is an increasingly prevalent global health problem, which is generally caused by the increase in body fat mass above normal and observed in all societies. If the blood glucose level is higher than normal but not high enough to diagnose diabetes, this condition is defined as prediabetes. Adiponectin increases fatty acid oxidation and insulin sensitivity and is closely associated with obesity. One of the nuclear receptor superfamily member peroxisome proliferator-activated receptors is shown to have an important role in various metabolic reactions. This study aimed to investigate the serum levels of adiponectin and peroxisome proliferator-activated receptors-gamma parameters, which are closely related to adipose tissue, energy metabolism, and insulin sensitivity, in obese patients with and without prediabetes. METHODS: For this purpose, 52 obese patients with prediabetes, 48 obese patients with non-prediabetes, and 76 healthy individuals were included in this study. Serum adiponectin and peroxisome proliferator-activated receptors-γ levels were analyzed by ELISA. RESULTS: Serum adiponectin levels were significantly higher in obese patients with prediabetes (18.15±15.99) compared with the control group (15.17±15.67; p=0.42). No significant difference was observed in both adiponectin and peroxisome proliferator-activated receptors-γ levels in the obese patients with the non-prediabetes group compared with the control group. However, no significant difference was observed in the obese patients with prediabetes group and obese patients with non-prediabetes group. CONCLUSION: Our results suggest that adiponectin may serve as an indicator of prediabetes. This implies that examining adiponectin levels in individuals diagnosed with prediabetes may enhance our understanding of the metabolic processes closely linked to prediabetes and related conditions.

The outcomes of an impaired powerhouse in KRAS mutant lung adenocarcinoma cells by Elesclomol.

OBJECTIVES: Lung cancer stands out as the most common cancer type worldwide. The most common genetic alteration detected in adenocarcinoma patients is KRAS. KRAS mutated patients still cannot get benefit from precision medicine approaches and lack a targeted therapy. Elesclomol is an investigational agent for melanoma and other malignancies. In this study, we evaluated its effect on cellular apoptosis, survival, and metastasis mechanisms on KRAS mutant A549 and Calu-1 cell lines. METHODS: The cytotoxic effects of Elesclomol on A549 and Calu-1 cells were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cell viability test. Cells were treated with IC50 concentration and then apoptosis-related (Casp-3, Casp-9, Bcl-2, and Bcl-xL), survival-related (Akt, p-Akt, Erk, and p-Erk), and metastasis-related (E-cadherin, Vimentin, MMP-2, and MMP-9) protein expressions were determined by Western blot analysis. Elesclomol's effect on cell migration was evaluated by wound healing. Total oxidant, malondialdehyde (MDA), and glutathione (GSH) levels after Elesclomol treatment were assessed. RESULTS: Elesclomol not only induced apoptotic proteins but also inhibited metastatic protein expressions and migration in both cells. Also, p-Erk activity was diminished by Elesclomol treatment as a reflection of decreased proliferation. However, p-Akt was enhanced as a cellular survival mechanism. Although Elesclomol's effects on oxidative stress parameters were puzzling, it induced total oxidant status (TOS), and MDA in Calu-1 cells. CONCLUSION: Elesclomol might provide an alternative treatment approach for patients with KRAS mutant lung adenocarcinoma and other solid tumor malignancies that harbor KRAS mutations. This would enable the development of biomarker-driven targeted therapy for KRAS mutant adenocarcinoma patients.
