RESUMEN
Colorectal cancer is typically treated through surgery, and self-care skills play a crucial role in disease adaptation and quality of life improvement. Therefore, this study aimed to investigate the effectiveness of a multimedia patient education intervention on enhancing the self-care and quality of life among patients with a postoperative stoma as well as on establishing an easy-to-use ostomy self-care skills assessment. The sample comprised 108 patients with new ostomies who were randomly assigned to two groups. Data were collected from June 2018 to March 2019. The conventional education service program group received individual education in the hospital environment, consisting of four 3-h sessions delivered over 4 consecutive days. The multimedia group viewed a multimedia educational program using a laptop. Data were collected at baseline and 3 months after the intervention using a demographic questionnaire, an ostomy self-care ability scale and the Stoma Quality of Life Scale. Before the intervention, there were no significant differences in self-care ability and quality of life scores between the two groups (p = 0.764 and p = 0.466, respectively). However, 3 months after the intervention, the group that received the multimedia software intervention showed significantly higher self-care ability and quality of life scores compared to the group that received conventional education services (p < 0.001). When a set threshold is reached, self-care ability and a good quality of life can be met. The threshold value of the ostomy self-care skill scale was determined to be 20 points, resulting in a sensitivity of 77.8% and a specificity of 75.5%. The results indicate that the multimedia education program enhanced home self-care ability and quality of life among patients with enterostomy.

Discovery of small molecule inhibitors targeting Mcl-1 (Myeloid cell leukemia 1) confronts many challenges. Based on the fact that Mcl-1 is mainly localized in mitochondria, we propose a new strategy of targeting mitochondria to improve the binding efficiency of Mcl-1 inhibitors. We report the discovery of complex 9, the first mitochondrial targeting platinum-based inhibitor of Mcl-1, which selectively binds to Mcl-1 with high binding affinity. Complex 9 was mainly concentrated in the mitochondria of tumor cells which led to an enhanced antitumor efficacy. Complex 9 induced Bax/Bak-dependent apoptosis in LP-1 cells and synergized with ABT-199 to kill ABT-199 resistant cells in multiple cancer models. Complex 9 was effective and tolerable as a single agent or in combination with ABT-199 in mouse models. This research work demonstrated that developing mitochondria-targeting Mcl-1 inhibitors is a new potentially efficient strategy for tumor therapy.

Lissencephaly (LIS), denoting a "smooth brain," is characterized by the absence of normal cerebral convolutions with abnormalities of cortical thickness. Pathogenic variants in over 20 genes are associated with LIS. The majority of posterior predominant LIS is caused by pathogenic variants in LIS1 (also known as PAFAH1B1), although a significant fraction remains without a known genetic etiology. We now implicate CEP85L as an important cause of posterior predominant LIS, identifying 13 individuals with rare, heterozygous CEP85L variants, including 2 families with autosomal dominant inheritance. We show that CEP85L is a centrosome protein localizing to the pericentriolar material, and knockdown of Cep85l causes a neuronal migration defect in mice. LIS1 also localizes to the centrosome, suggesting that this organelle is key to the mechanism of posterior predominant LIS.

A facile and effective impregnation combined with photo-deposition approach was adopted to deposit cadmium sulfide (CdS) nanoparticles on CTF-1, a covalent triazine-based frameworks (CTFs). In this system, CTF-1 not only acted as supporter but also served as photocatalyst and electron donor. The performance of the obtained CdS deposited CTF-1 (CdS-CTF-1) nanocomposite was evaluated by H2 evolution reaction under visible light irradiation. As a result, CdS-CTF-1 exhibited high H2 production from water, far surpassing the CdS/CTF-1 nanocomposite, in which CdS was deposited via solvothermal method. The high activity of CdS-CTF-1 was attributed to the confined CdS nanoparticles with small size, leading to expose more active sites. In addition, time-resolved spectroscopy indicated that the superior performance of CdS-CTF-1 also can be ascribed to the fast electron transfer rate and injection efficiency (KETâ¯=â¯0.18â¯×â¯109â¯s-1, ηinjâ¯=â¯39.38%) between CdS and CTF-1 layers, which are 3.83 times faster and 4.84 times higher than that of CdS/CTF-1 nanocomposite. This work represents the first example on using covalent organic frameworks (COFs) as a support and electron-donor for fabricating novel CdS-COF nanocomposite system and its potential application in solar energy transformations.
RESUMEN
BACKGROUND: To investigate the association between metabolic syndrome, including its factors, and gallstone disease (GSD) in a Taiwanese population. METHODS: We conducted a cross-sectional study during 2011 ~ 2012. A total of 12050 subjects who completed a questionnaire and underwent physical examination, laboratory tests and abdominal ultrasonography formed the study population. RESULTS: The prevalences of metabolic syndrome and gallstone disease were 24.09% and 6.16%. In an age- and sex-adjusted logistic regression model, metabolic syndrome was associated with gallstone disease (OR = 1.61; P < 0.0001). Age, abdominal obesity, and lower high-density lipoprotein cholesterol were associated with gallstone disease after adjusting for other factors. Females had a higher odds ratio than males in waist circumference for GSD, whereas males had a lower odds ratio than females in HDL-C for GSD. CONCLUSIONS: The present study suggests that metabolic syndrome is related to gallstone disease. Waist circumference and high-density lipoprotein cholesterol are all associated with GSD. Men and women may possibly have different priorities and strategies to reduce the burden of GSD.

RESUMEN
A novel one-dimensional (1-D) mixed-valent thioarsenate (III, V), {[Mn(phen)](3)(As(V)S(4))(As(III)S(3))}(n)·nH(2)O (1), with a noncentrosymmetric (NCS) polar packing arrangement has been obtained under solvothermal conditions. The noncondensed (As(III)S(3))(3-) anion in 1 is stabilized by coordinating to [Mn(II)(phen)](2+) complex cations and exhibits an unprecedented µ(3)-1,2κS:2,3κS':3κS'' linkage mode. Compound 1 represents the first example of the stabilization of noncondensed (MQ(3))(3-) (M = As, Sb; Q = S, Se) species only in the coordination of TM(II) complex cations (TM = transition-metal) and the first observation of the coexistence of the (As(V)S(4))(3-) tetrahedron and the noncondensed (As(III)S(3))(3-) pyramid in a single compound. Of particular interest, compound 1 is also an antiferromagnet with T(N) = 31 K, and exhibits photoluminescence (PL) with a maximum emission at about 438 nm and a second harmonic generation (SHG) response.
RESUMEN
The asymmetric unit of the title Cd(II) compound, [Cd(N(3))(2)(C(12)H(8)N(2))](n), contains a Cd(II) atom, located on a twofold axis passing through the middle of the phenanthroline mol-ecule, one azide ion and half of a 1,10-phenanthroline mol-ecule. The Cd(II) atom exhibits a distorted octa-hedral coordin-ation including one chelating 1,10-phenanthroline ligand and four azide ligands. The crystal structure features chains along the c direction in which azide groups doubly bridge two adjacent Cd(II) atoms in an end-on (EO) mode. Inter-chain π-π stacking inter-actions, with centroid-centroid separations of 3.408â (2)â Å between the central aromatic rings of 1,10-phenanthroline mol-ecules, lead to a supra-molecular sheet parallel to the bc plane.
