Effects of different precursors on the structure of lignin-based biochar and its ability to adsorb benzopyrene from sesame oil.

Agricultural by-products of sesame are promising bioresources in food processing. This study extracted lignin from the by-products of sesame oil production, namely, the capsules and straw of black and white sesame. Using acid, alkali, and ethanol methods, 12 distinct lignins were obtained to prepare biochar, aiming to investigate both the structural characteristics of lignin-based biochar (LBB) and its ability to remove benzo[a]pyrene (BaP) from sesame oil.

Comparison of methods for activating sesame stalk lignin biochar for removing benzo[a]pyrene from sesame oil.

In this study, three activators and two activation methods were employed to activate sesame lignin-based biochar. The biochar samples were comprehensively characterized, their abilities to adsorb benzo[a]pyrene (BaP) from sesame oil were assessed, and the mechanism was analyzed. The results showed that the biochar obtained by one-step activation was more effective in removing BaP from sesame oil than the biochar produced by two-step activation.

Identification of a novel ferroptosis-related gene signature associated with retinal degeneration induced by light damage in mice.

Background: Neurodegenerative retinal diseases such as retinitis pigmentosa are serious disorders that may cause irreversible visual impairment. Ferroptosis is a novel type of programmed cell death, and the involvement of ferroptosis in retinal degeneration is still unclear. This study aimed to investigate the related ferroptosis genes in a mice model of retinal degeneration induced by light damage.

Atypical Angucyclinones with Ring Expansion and Cleavage from a Marine sp.

A unique ring C-expanded angucyclinone, oxemycin A (), and seven new ring-cleavage derivatives (- and -) were isolated from the marine actinomycete KCB-132, together with eight known analogues (- and -). Their structures were elucidated by spectroscopic analyses, single-crystal X-ray diffractions, and NMR and ECD calculations. Among these atypical angucyclinones, compound represented the first seven-membered ketoester in the angucyclinone family, which sheds light on the origin of fragmented angucyclinones with C-ring cleavage at C-12/C-12a in the Baeyer-Villiger hypothesis, such as -, while the related "nonoxidized" analogues - seem to originate from a diverse pathway within the Grob fragmentation hypothesis.

Information fields of written texts protect cells from oxidative damage and accelerate repair.

Objective: Written words demonstrated specific effects on biochemical measures and cell growth in cultured mammalian cells in previous study. We examined the protection and reparative effects of Chinese texts with positive meaning and the word "Buddha" on oxidative-damaged cells, with the goal of exploring the therapeutic effect of such characters.

Methods: The human embryonic kidney cell line HEK293T was utilized, with the oxidative- damaged cell model produced by hydrogen peroxide (HO).

Strepyrazinone, a tricyclic diketopiperazine derivative with cytotoxicity from a marine-derived actinobacterium.

Strepyrazinone (, a tricyclic diketopiperazine derivative with a carbon skeleton unprecedented in natural products, was isolated from the marine-derived sp. B223. Its structure was elucidated by spectroscopic analyses and electronic circular dichroism calculation.

Isolation, stereochemical study, and racemization of (±)-pratenone A, the first naturally occurring 3-(1-naphthyl)-2-benzofuran-1(3H)-one polyketide from a marine-derived actinobacterium.

(±)-Pratenone A (1), the first representative of natural 3-(1-naphthyl)-2-benzofuran-1(3H)-one polyketides, was isolated from a marine-derived Streptomyces pratensis strain KCB-132 together with three other new analogues (2-4). Its structure was assigned by spectroscopic analysis, and the absolute configurations of the two enantiomers separated by high-performance liquid chromatography were determined by single-crystal X-ray diffraction and electronic circular dichroism calculations. The solvent-induced racemization of 1 and a proposed biogenetic pathway to 1-4 from the co-isolated angucyclinone precursor, as well as their biological activity, are also discussed.

Novel Insights reveal Anti-microbial Gene Regulation of Piglet Intestine Immune in response to Clostridium perfringens Infection.

LncRNA play important roles in regulation of host immune and inflammation responses in defending bacterial infection. Clostridium perfringens (C. perfringens) type C is one of primary bacteria leading to piglet diarrhea and other intestinal inflammatory diseases.

The complete mitochondrial genome of the Qinghai Tibetan pig.

The complete mitochondrial genome sequence of the Qinghai Tibetan pig was first determined in this study. The total length of the mitogenome is 16,720 bp. Indicating the an A + T(60.

[Classification, distribution and change of Uighur medicinal materials resources].

With the development and change of Uygur medicine, The sources,medicinal parts and producing area of some Uygur Medicine have changed. It is more important to master the classification, distribution and change of Uygur medicinal materials. These were more than 1 200 kinds Uygur medicine in history were resaerched by field investigation, philological research, and textual research, which main source of original plant were 140 families, 510 genera, 840 species; and source of original animal were 76 families, 107 genera, the original animal 141 species; 55 kinds of original mineral, which main producer were Xinjiang and Central Asia, West Asia, the Mediterranean, and North Africa, Southeast Asia and other provinces in China, there are individual medicinal materials from the Americas, Europe and other places.

Protective Effects of the Ethanol Extract of Viola tianshanica Maxim against Acute Lung Injury Induced by Lipopolysaccharides in Mice.

Maxim, belonging to the Violaceae plant family, is traditionally used in Uighur medicine for treating pneumonia, headache, and fever. There is, however, a lack of basic understanding of its pharmacological activities. This study was designed to observe the effects of the ethanol extract (TSM) from Maxim on the inflammation response in acute lung injury (ALI) induced by LPS and the possible underlying mechanisms.
