Background: Functioning gonadotroph adenomas are extremely rare pituitary tumors that secrete gonadotropins and exhibit distinct clinical manifestations. Here, we report a case of functioning gonadotroph adenoma in a reproductive-aged woman and discuss its diagnosis and management.

Case Summary: A 21-year-old female patient with abdominal pain, irregular menstruation, hyperestrogenemia, and an ovarian mass was included.

Background: The time interval rules and survival outcomes of individuals with synchronous and metachronous breast cancer (BC) and ovarian cancer (OC) were examined in this retrospective population-based investigation.

Methods: The National Cancer Institute's Surveillance, Epidemiology, and End Results database was used to create a cohort of people diagnosed with BC and OC between 1973 and 2015. Patients were separated into three groups: those with main BC followed by primary OC (group 1), those with synchronous primary breast and ovarian cancer (group 2), and those with OC prior to BC (group 3).

The aim of this retrospective population-based study was to investigate the survival outcomes and prognostic factors of patients with the two cervical carcinomas. A cohort of patients diagnosed with papillary serous adenocarcinoma of the uterine cervix (PSAC) and papillary squamous cell carcinoma (PSCC) between 1973 and 2015 were drawn from the National Cancer Institute's Surveillance Epidemiology and End Results (SEER) database. Overall survival (OS) and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method, and prognostic factors were assessed using Cox proportional hazards survival regression analysis.

Background: The role that lymph node dissection (LND) plays in the management of ovarian carcinosarcoma (OCS) is unclear due to its rarity. This study investigated lymph node metastasis (LNM) prevalence in women with early OCS and effects of LND and LNM on survival.

Methods: Data of women diagnosed with OCS, whose primary tumor was confined to ovaries (American Joint Committee on Cancer [AJCC] T1) or pelvic cavity (AJCC T2), between 1988 and 2010 were collected from the Surveillance, Epidemiology, and End Results (SEER) database.

Coconut shell based biochar was modified by ultraviolet irradiation with UV light at a wavelength of 365 nm in order to enhance the adsorption capacity for volatile organic compounds (VOCs). The breakthrough curves of biochars for adsorbing two typical VOCs (benzene and toluene) were examined. The results showed that the adsorption capacity of modified biochar was greatly increased.

Unlabelled: Bats harbor severe acute respiratory syndrome (SARS)-like coronaviruses (SL-CoVs) from which the causative agent of the 2002-2003 SARS pandemic is thought to have originated. However, despite the fact that a large number of genetically diverse SL-CoV sequences have been detected in bats, only two strains (named WIV1 and WIV16) have been successfully cultured in vitro These two strains differ from SARS-CoV only in containing an extra open reading frame (ORF) (named ORFX), between ORF6 and ORF7, which has no homology to any known protein sequences. In this study, we constructed a full-length cDNA clone of SL-CoV WIV1 (rWIV1), an ORFX deletion mutant (rWIV1-ΔX), and a green fluorescent protein (GFP)-expressing mutant (rWIV1-GFP-ΔX).

Objective: To study the chemical constituents of ethanolic extract from herbs of Dicliptera chinensis.

Method: The compounds were separated by silica gel column chromatography, preparation TLC and reverse phase HPLC, their structures were identified by the spectroscopic methods of UV, NMR and MS.

Result: Seven compounds were isolated from ethyl acetate extract.
