Bariatric surgeries and cardiac structure and function: Systematic review and network meta-analysis.

Background: Obesity, a global health problem, is causally implicated in the development of cardiovascular disease. Bariatric surgeries are effective treatment options for obesity; however, the effectiveness of different bariatric surgeries on cardiac structure and function is not fully understood. We undertook a systematic review and network meta-analysis to comprehensively assess this effectiveness.

[A preliminary study on the relationship between HLA-Cw polymorphism and susceptibility to pulmonary tuberculosis].

Objective: To analyze the relationship between HLA-Cw polymorphism and susceptibility to pulmonary tuberculosis (PTB), and therefore to explore the susceptible or resistant genes of PTB.

Methods: A hundred and twelve patients who were confirmed to have secondary PTB in Shandong Chest Hospital from May 2010 to May 2011 were selected as the PTB group, including 62 males and 50 females aged 19 - 69 years (mean 41.7).

Poly[μ(3)-hydroxido-μ-(pyridine-2,4,6-tricarboxyl-ato)-dilead(II)].

The asymmetric unit of the title coordination polymer, [Pb(2)(C(8)H(2)NO(6))(OH)](n), contains two crystallographically independent Pb(II) ions, one pyridine-2,4,6-tricarboxyl-ate (ptc) trianion and one hydroxide anion. One of the Pb(II) atoms is coordinated by one pyridine N and four carboxyl-ate O atoms from the ptc trianion and a hydroxide O atom in a distorted octa-hedral geometry. The other Pb(II) atom is five-coordinated by three carboxyl-ate O atoms and two hydroxide O atoms in a distorted tetra-gonal-pyramidal geometry.
