[Advances in Nanotechnology-Based Drug Delivery Systems in the Treatment of Hepatocellular Carcinoma].

Primary liver cancer is one of the most common malignant tumors of the digestive system,of which hepatocellular carcinoma (HCC) accounts for more than 90% of the total cases.The patients with early HCC treated by surgical resection generally demonstrate good prognosis.However,due to the insidious onset,HCC in the vast majority of patients has progressed to the mid-to-late stage when being diagnosed.

A retrospective analysis of 25 cases of Addison's disease caused by adrenal tuberculosis in Tibet and review of related literature.

Background: To investigate the clinical characteristics of Addison's disease caused by adrenal tuberculosis in Tibet. After the anti-tuberculosis treatment, the clinical features between continuous glucocorticoid therapy and glucocorticoid withdrawal were analyzed.

Methods: Clinical data of patients with Addison's disease caused by adrenal tuberculosis diagnosed in The People's Hospital of Tibet Autonomous Region from January 2015 to October 2021 were collected and analyzed.

Exosomes Derived from M2 Macrophages Exert a Therapeutic Effect via Inhibition of the PI3K/AKT/mTOR Pathway in Rats with Knee Osteoarthritic.

Macrophages are commonly classified as M1 macrophages or M2 macrophages. M2 macrophages are obtained by stimulation of IL-4 with anti-inflammatory and tissue repair effects. Exosomes are 30-150 nm lipid bilayer membrane vesicles derived from most living cells and have a variety of biological functions.

Supportive role of the Na transporter CmHKT1;1 from Cucumis melo in transgenic Arabidopsis salt tolerance through improved K/Na balance.

CmHKT1;1 selectively exports Na from plant cells. Upon NaCl stress, its expression increased in a salt-tolerant melon cultivar. Overexpression of CmHKT1;1 increased transgenic Arabidopsis salt tolerance through improved K/Na balance.

Effect of sulfate addition on methane production and sulfate reduction in a mesophilic acetate-fed anaerobic reactor.

A mesophilic anaerobic moving bed biofilm reactor (MBBR) was operated to evaluate the effect of sulfate addition on methane production and sulfate reduction using acetate as the sole carbon source. The results show that at the organic loading rate of 4.0 g TOC/L/day, the TOC removal efficiencies and the biogas production rates achieved over 95 % and 7000 mL/L/day without sulfate, respectively, and slightly decreased with sulfate addition (500-800 mg/L).

Poly[[μ-1,4-bis-(1H-imidazol-4-yl)benzene-κN:N](μ-5-methyl-isophthalato-κO:O)cobalt(II)].

In the title coordination polymer, [Co(C(9)H(6)O(4))(C(12)H(10)N(4))](n), the Co(II) atom is four-coordinated by two O atoms from two different 5-methyl-isophthalate bivalent anions and two N atoms from two different 1,4-bis-(1H-imidazol-4-yl)benzene ligands, forming a four-coordinated tetra-hedral coordination geometry. Each 5-methyl-isophthalate ligand acts as a μ(2)-bridge, linking two Co(II) atoms and forming chains which are further linked by 1,4-bis-(1H-imidazol-4-yl)benzene ligands into a two-dimensional network parallel to ([Formula: see text]01). These planes are, in turn, linked by two inter-molecular N-H⋯O inter-actions, forming a three-dimensional structure.

In the title coordination polymer, [Cd(C(9)H(6)O(4))(C(12)H(10)N(4))(H(2)O)](n), the Cd(II) atom has a NO(6) donor set and is coord-inated by five carboxyl-ate O atoms from three different 5-methyl-1,3-phenyl-enediacetate (pda(2-)) anions, one O atom from a water mol-ecule and one N atom from a 1,4-bis-(1H-imidazol-4-yl)benzene (L) ligand, displaying a highly distorted penta-gonal-bipyramidal geometry. Each pda(2-) anion acts as a μ(3)-bridge, linking Cd(II) atoms to form one-dimensional slabs extending parallel to [010]. In the crystal, adjacent mol-ecules are linked through N-H⋯N and N-H⋯O hydrogen bonds into a three-dimensional network.

Poly[bis-[μ-1,4-bis-(1H-imidazol-5-yl)benzene-κN:N]diformatomanganese(II)].

In the title compound, [Mn(CHO(2))(2)(C(12)H(10)N(4))(2)](n), the Mn(II) atom and the benzene ring of the ligand lie on an inversion centers. The Mn(II) atom has an octa-hedral coordination environment composed of four N atoms from two different symmetry-related N-heterocyclic ligands forming the basal plane, and two O atoms from symmetry-related formate anions occupying the apical positions. The title compound forms a two-dimensional (4,4) net parallel to (100) with all the Mn(II) atoms lying on a plane.
