Muscle Contraction Is Essential for Tendon Healing and Muscle Function Recovery After Achilles Tendon Rupture and Surgical Repair.

Incomplete tendon healing and postponed muscle weakness after Achilles tendon rupture and surgical repair lead to poor performance in patient activities. Although the effectiveness of postoperative early functional rehabilitation has been proven, the priority and each effect of specific methods in early rehabilitation remain unclear. We hypothesized early muscle contraction exercises without joint motion would promote tendon healing and prevent calf muscle atrophy; in contrast, early static stretching after surgical repair would not contribute to tendon healing and induce calf muscle atrophy.

Carboplatin in combination with etoposide for advanced small cell lung cancer complicated with idiopathic interstitial pneumonia: a single-arm phase II study.

Background: Acute exacerbation (AEx) of interstitial pneumonia is the most common lethal adverse event related to the pharmacological treatment of patients with lung cancer complicated with interstitial pneumonia. Although small cell lung cancer (SCLC) is linked to poor prognosis, it exhibits good response to chemotherapy. Few previous research studies have investigated the safety and efficacy of treatment for advanced SCLC complicated with idiopathic interstitial pneumonia (IIP).

Lower mean corpuscular hemoglobin levels as a predictive factor of future exacerbations in patients with chronic obstructive pulmonary disease.

Background: Chronic obstructive pulmonary disease (COPD) is a pulmonary and systemic inflammatory disease, and the management of systemic comorbidities is important. We previously reported that a lower mean corpuscular hemoglobin concentration (MCHC) at admission was an independent prognostic factor for death in patients with COPD exacerbation. This study aimed to determine the association between MCHC levels and prognosis in patients with stable COPD.

Ruscus aculeatus extract promotes RNase 7 expression through ERK activation following inhibition of late-phase autophagy in primary human keratinocytes.

Antimicrobial peptides (AMPs) are crucial for protecting human skin from infection. Therefore, the expression levels of beneficial AMPs such as ribonuclease 7 (RNase 7) must be appropriately regulated in healthy human skin. However, there is limited understanding regarding the regulating AMP expression, especially when using applications directly to healthy human skin.

Commensal Neisseria Inhibit Porphyromonas Gingivalis Invasion of Gingival Epithelial Cells.

Purpose: Periodontal disease is caused by periodontal invasion by pathogens such as Porphyromonas gingivalis. Although recent metagenomic analyses have shown that oral commensal bacteria are abundant in the mouth of healthy individuals, few studies have experimentally verified the benefits and functions of oral commensal bacteria in periodontal diseases. In this study, we focused on Neisseria among the oral commensal bacteria and aimed to experimentally verify its effects on P.
