Comparative effectiveness of low-level laser therapy for adult androgenic alopecia: a system review and meta-analysis of randomized controlled trials.

The purpose of this review is to explore the effectiveness of low-level laser therapy (LLLT) in the treatment of adult androgenic alopecia (AGA). A systematic search of studies on LLLT for AGA was conducted mainly in Pubmed, Embase, and Cochrane Systematic Reviews. The standardized mean difference (SMD) in the changes of hair density treated by LLLT versus sham devices was analyzed.

Hypoxia Stimulates the Epithelial-to-Mesenchymal Transition in Lung Cancer Cells Through Accumulation of Nuclear β-Catenin.

Background/aim: Recent studies implied a significant role of hypoxia-inducible factor-1α (HIF1α) in cell transformation. This study aimed to assess the effects of HIF1α on the epithelial-to-mesenchymal transition (EMT) and tumorigenesis of lung adenocarcinoma cells.

Materials And Methods: Invasion, migration and colony formation assays were used to evaluate cell transformation.

Utility of Gram staining for diagnosis of Malassezia folliculitis.

Malassezia folliculitis (MalF) mimics acne vulgaris and bacterial folliculitis in clinical presentations. The role of Gram staining in rapid diagnosis of MalF has not been well studied. In our study, 32 patients were included to investigate the utility of Gram staining for MalF diagnosis.

Early decline in serum phospho-CSE1L levels in vemurafenib/sunitinib-treated melanoma and sorafenib/lapatinib-treated colorectal tumor xenografts.

Background: Although targeted therapies have improved the clinical outcomes of cancer treatment, tumors resistance to targeted drug are often detected too late and cause mortality. CSE1L is secreted from tumor and its phosphorylation is regulated by ERK1/2. ERK1/2 is located downstream of various growth factor receptors and kinases, the targets of most targeted drugs.

High expression of cytoplasmic phosphorylated CSE1L in malignant melanoma but not in benign nevi: phosphorylated CSE1L for the discrimination between melanoma and benign nevi.

Melanoma is difficult to treat when it has metastasized. Discrimination between melanoma and benign nevi in melanocytic lesions is crucial for identifying melanomas and consequently improving melanoma treatment and prognosis. The chromosome segregation 1-like (CSE1L) protein has been implicated in cancer progression and is regulated by phosphorylation by extracellular signal-regulated kinase 1/2 (ERK1/2) signaling, a critical pathway in melanoma progression.

Usefulness of p16 for differentiating primary pulmonary squamous cell carcinoma from cervical squamous cell carcinoma metastatic to the lung.

To date, there is no reliable immunohistochemical marker that discriminates between primary pulmonary squamous cell carcinoma (SCC) and cervical SCC metastatic to the lung. In this study, immunohistochemical staining of p16 was performed on 33 primary pulmonary SCCs, 48 primary cervical SCCs, and 17 cases of cervical SCC with pulmonary metastasis. Expression of p16 was noted in 47 cases of cervical SCC (47/48 [98%]), and all were strongly stained.
