A gynandromorph of the stonefly Amphinemura zonata (Okamoto, 1922) (Plecoptera: Nemouridae) from Japan.

A gynandromorph of Amphinemura zonata (Okamoto, 1922) collected from Matsubara-izumi Pond in Japan is described and illustrated as the first report in the genus. The specimen exhibits bilateral gynandromorphism on abdominal sterna 79 and the paraprocts. Male features occur on the right half and female features on the left half.

Liver injury with COVID-19 based on gastrointestinal symptoms and pneumonia severity.

Background/aim: The coronavirus disease 2019 (COVID-19) had become a big threat worldwide. Liver injury is not uncommon in patients with COVID-19, and clarifying its characteristics is needed. This study aimed to identify factors associated with liver injury and to develop a new classification of predictive severity in patients with COVID-19.

Clinical validation of an immunochromatographic SARS-Cov-2 IgM/IgG antibody assay with Japanese cohort.

Background: The coronavirus disease 2019 (COVID-19) has become a major health threat. To overcome COVID-19, appropriate diagnosis methods are urgently needed. The aim of this study was to clinically evaluate the colloidal gold immunochromatography assay for SARS-Cov-2 IgM/IgG antibody (Ab).

[A case of Carboplatin and pemetrexed combination chemotherapy for synchronous double cancers of hepatocellular carcinoma and primary lung cancer].

A 78-year-old man presented to our hospital with lung abnormality on his chest radiograph. Computed tomography (CT) showed a mass and obstructive pneumonia in the right upper lobe of the lung. The mass was diagnosed as a pulmonary adenocarcinoma with a bronchoscopy (cT4N2M0, Stage IIIB).

[A case of advanced gastric cancer with carcinomatous lymphangitis of the lung treated with docetaxel and S-1 combination chemotherapy].

A 67-year-old woman with complaints of cough and dyspnea was admitted; her chest radiographs and computed tomography (CT) scans revealed pulmonary carcinomatous lymphangitis. Endoscopic examination revealed advanced gastric cancer and the patient was treated with a combination of 40 mg/m2 docetaxel, administered on day 1, and S-1 100 mg/body/day, administered for 14 days followed by a 7-day interval, as 1 course despite her performance status( PS) being grade 3. After 2 courses of chemotherapy, CT showed that the carcinomatous lymphangitis had improved, and the patient was discharged with PS of grade 0.

Gene expression profiling of epidermal growth factor receptor/KRAS pathway activation in lung adenocarcinoma.

We examined the genome-wide expression profiles of 86 primary lung adenocarcinomas and compared them with the mutation status of the four key molecules (EGFR, ERBB2, KRAS and BRAF) in the EGFR/KRAS/BRAF pathway. Unsupervised classification revealed two subtypes (the bronchial type and the alveolar type) of lung adenocarcinoma. Mutually exclusive somatic mutations of the epidermal growth factor receptor (EGFR) gene (36/86, 41.

Gene transfer of Smad7 using electroporation of adenovirus prevents renal fibrosis in post-obstructed kidney.

Background: Unilateral ureteral obstruction (UUO) leads to interstitial fibrosis of the obstructed kidney, and TGF-beta is considered to play an important role in this fibrotic process. Smad7 has been recently identified as an antagonist of TGF-beta signaling. To investigate whether this novel molecule can be exploited for therapy of renal fibrosis, we determined the effect of exogenous Smad7, introduced by a recombinant adenovirus vector combined with in vivo electroporation (EP), on UUO-induced renal fibrosis in rats.
