BACKGROUND: The treatment of patients with advanced gastric cancer remains a most challenging task in the clinical practice. Recently, targeted therapies have significantly impacted the treatment strategy for many common malignancies. The use of trastuzumab, a monoclonal antibody against human epidermal growth factor receptor 2 (HER2; also known as ERBB2), plus chemotherapy proved to improve median overall survival in patients with advanced gastric cancer, compared with chemotherapy alone in Trastuzumab for Gastric Cancer (ToGA) trial...

STUDY OBJECTIVES: To evaluate the clinical characteristics of women presenting with catamenial pneumothorax and compare them with those with non-catamenial pneumothorax. DESIGN: Case control study (Canadian Task Force II-2). SETTING: Multicenter study PATIENTS: 42 women with pneumothorax; 21 women had catamenial pneumothorax (study group) and 21 age-matched women with non-catamenial pneumothorax (control group).

OBJECTIVE: Robotic surgery is increasingly being used for treatment of malignant and benign gynaecologic diseases. The purpose of our study is to compare patient perioperative complications and costs of laparoscopic versus robotic-assisted hysterectomy for uterine leiomyomas. METHODS: A retrospective cohort study using the Nationwide Inpatient Sample database from the United States was conducted, comparing patients who underwent robotic-assisted hysterectomy and laparoscopic hysterectomy (total laparoscopic hysterectomy and laparoscopic-assisted vaginal hysterectomy) for uterine fibroids between 2008 and 2012...

BACKGROUND: Genetic variation in the β2-adrenergic receptor (ADRB2) gene has been thought to have an important role in the differential response to β2-agonist therapy for asthma. However, previous studies have shown little evidence for an association between these ADRB2 variants and the bronchial dilator response (BDR) in chronic obstructive pulmonary disease (COPD) patients. This discrepancy could be explained by differences in the distribution and heterogeneity of pulmonary emphysema in COPD patients, since emphysema distribution and heterogeneity are thought to have a role in pulmonary function in COPD patients...

The preservation of the spatial relationships among axonal pathways has long been studied and known to be critical for many functions of the brain. Being a fundamental property of the brain connections, there is an intuitive understanding of topographic regularity in neuroscience but yet to be systematically explored in connectome imaging research. In this work, we propose a general mathematical model for topographic regularity of fiber bundles that is consistent with its neuroanatomical understanding. Our model is based on a novel group spectral graph analysis (GSGA) framework motivated by spectral graph theory and tensor decomposition...

BACKGROUND: S-1 plus cisplatin is a standard regimen for advanced gastric cancer (AGC) in Asia. The ToGA trial established a fluoropyrimidine plus cisplatin and trastuzumab as a standard treatment for human epidermal growth factor receptor 2 (HER2)-positive AGC. In the HERBIS-1 trial, trastuzumab combined with S-1 plus cisplatin showed promising antitumor activity in patients with HER2-positive AGC. However, cisplatin has several important drawbacks, including vomiting and renal toxicity...

Importance: It is unclear whether female carriers of the apolipoprotein E (APOE) ε4 allele are at greater risk of developing Alzheimer disease (AD) than men, and the sex-dependent association of mild cognitive impairment (MCI) and APOE has not been established. Objective: To determine how sex and APOE genotype affect the risks for developing MCI and AD.

OBJECTIVE: To investigate coagulation system changes during an in-vitro fertilization (IVF) cycle using Thromboelastogram (TEG) that enables analysis of the elastic properties of whole blood samples and provides a global assessment of the hemostatic function. STUDY DESIGN: A prospective study. TEG indices were evaluated in 23 women who underwent controlled ovarian stimulation for IVF at four points in time: 1. At the beginning of the cycle (corresponding to the lowest levels of E2), 2...

REVIEW
Grace Younes, Togas Tulandi
The traditional treatment for women with symptomatic adenomyosis is hysterectomy. However, reproductive aged women should be managed with less invasive treatments including medical treatment. For patients who are refractory or unsuitable to long term medical treatment, or those with focal adenomyoma, conservative surgeries could be offered. The objective of our study was to review available conservative surgeries for the treatment of adenomyosis, their complications, and the rates of success and recurrence...

Eukaryotic protein phosphatase 4 (PP4) is a PP2A-type protein phosphatase that is part of a conserved complex with regulatory factors PSY2 and PP4R2. Various lines of Arabidopsis thaliana with mutated PP4 subunit genes were constructed to study the so far completely unknown functions of PP4 in plants. Mutants with knocked out putative functional homolog of the PSY2 LIKE (PSY2L) gene were dwarf and bushy, while plants with knocked out PP4R2 LIKE (PP4R2L) looked very similar to WT. The psy2l seedlings had short roots with disorganized morphology and impaired meristem...

BACKGROUND: Catamenial pneumothorax is a rare but serious condition for women of reproductive age. We describe a trial of dienogest as hormonal therapy for catamenial pneumothorax and review the literature on hormonal suppressive therapy for this condition. CASE: A 39-year-old female, gravida 0 para 0, presented with recurrent pneumothoraces coinciding with her menses. After surgical therapy, she was started on leuprolide acetate injections for 6 months to reduce recurrence...

Possible differences between serum HCG levels in pregnancies achieved after transfer of a single fresh or a vitrified-warmed blastocyst were evaluated. Out of 1130 single blastocyst transfers resulting in positive HCG results, 789 were single fresh blastocyst transfers and 341 single vitrified-warmed blastocyst transfers. The initial serum HCG levels of 869 clinical intrauterine pregnancies were evaluated, 638 after the transfer of a single fresh blastocysts and 231 after the transfer of a single vitrified-warmed blastocysts...

BACKGROUND: The APOE ε4 allele is the most significant common genetic risk factor for late-onset Alzheimer's disease (LOAD). The region surrounding APOE on chromosome 19 has also shown consistent association with LOAD. However, no common variants in the region remain significant after adjusting for APOE genotype. We report a rare variant association analysis of genes in the vicinity of APOE with cerebrospinal fluid (CSF) and neuroimaging biomarkers of LOAD. METHODS: Whole genome sequencing (WGS) was performed on 817 blood DNA samples from the Alzheimer's Disease Neuroimaging Initiative (ADNI)...

Thermotogales are rod-shaped, Gram-negative, anaerobic, (hyper) thermophiles distinguished by an outer sheath-like toga, which comprises an outer membrane (OM) and an amorphous layer (AL). Thermosipho globiformans bacteria can transform into spheroids with multiple cells concurrently with AL disintegration during early growth; the cell is defined as the cytoplasmic membrane (CM) plus the entity surrounded by the CM. Spheroids eventually produce rapidly moving periplasmic 'progenies' through an unknown mechanism...

A key to the successful use of targeted cancer therapy is the ability to preselect patients who are likely to benefit from the treatment according to molecular markers. Assessment for predicting therapy response is mostly done using tumor biopsies. However, these might not truly represent all of the patient's malignant cells because of tumor heterogeneity and/or clonal evolution during disease progression. One potential strategy that can complement primary tumor biopsy is the analysis of circulating tumor cells (CTCs)...
