Reaction of 5-phenyl-2,2'-bipyridine (L) with a mixture of CuI or [Cu(CH3CN)4]BF4 and PPh3 leads to mononuclear heteroleptic complexes [CuL(PPh3)I] (1) and [CuL(PPh3)2]BF4 (2). According to X-ray diffraction, L crystallizes in the monoclinic space group P21/n, exhibiting a disorder over four orientations. Complexes 1 and 2 crystallize in the monoclinic space groups P21/c and P21, respectively. ...

Endometriosis affects 10% of women of reproductive age. Its main feature is the presence of stroma and endometrial glands in sites other than the uterus, mainly in pelvis. Pelvic peritoneum, ovaries, uterine ligaments, bladder, intestines, and cul-de-sac are among the affected areas. Sometimes endometriosis can be found outside of the pelvis and even above abdominal cavity, like diaphragm. Here...

A total of 52 residual CSF and serum specimens, which were originally negative with the Cryptococcal Antigen Latex Agglutination System (CALAS), were shown to become falsely positive after placement in BBL Port-A-Cul anaerobic transport vials. This transport device, although excellent for specimen transportation for subsequent culture, should not be used if cryptococcal antigen testing is needed.

A viral agent inducing syncytia formation in monolayer cul tures of bovine embryonic spleen cells and a rabbit cornea cell line was isolated from cattle with lymphosarcoma. The agent was strongly cell-associated and transmissible with cell-free ff1trates at very low dilutions. An antigen prepared from heavily infected cultures produced precipitin lines by immunodiffu sion when tested against se...

ECS (Elongin BC-Cul2/Cul5-SOCS-box protein) ubiquitin ligases recruit substrates to E2 ubiquitin-conjugating enzymes through a SOCS-box protein substrate receptor, an Elongin BC adaptor and a cullin (Cul2 or Cul5) scaffold which interacts with the RING protein. In vitro studies have shown that the conserved amino acid sequence of the cullin box in SOCS-box proteins is required for complex forma...

In early C. elegans embryos, the transition from meiosis to mitosis requires degradation of the MEI-1 protein. A novel class of SCF-like ubiquitin ligases has been identified that mediates this process. These ligases contain the CUL-3 scaffold at their core and use a BTB-domain protein in substrate recognition.

BACKGROUND A case of pneumococcal septicemia associated with laparoscopically documented acute salpingitis is reported. CASE Gram-stained cul-de-sac pus revealed gram-positive encapsulated diplococci. CONCLUSION This case coupled with reanalysis of prior genital tract involvement in nonpregnant individuals argues that Streptococcus pneumoniae can mimic gonococcal diseases.

Recovery of six anaerobic and five aerobic pathogens from viscose swabs and polyurethane swabs (Culturette EZ) was evaluated quantitatively, and transport in aerobic dry tubes, aerobic Amies transport medium (Transwab), and anaerobic universal transport medium (Port-a-Cul) was compared. The Culturette EZ in aerobic dry tubes gave the highest recovery levels. Data obtained with clinical specimen...
