Spinel lithium manganate (LiMn2O4) is a promising cathode for aqueous lithium-ion batteries (ALIBs). However, due to Mn dissolution and the Jahn-Teller effect it suffers from fast capacity fading, insufficient rate capability, and low overcharge resistance. Herein, a ∼2-3 nm artificial solid electrolyte interphase (SEI) layer (lithium polyacrylate, LiPAA) is constructed on the commercial LiMn2O4 (LiPAA@LiMn2O4). It is realized by an in situ polymerization hydrothermal reaction using an acrylic monomer. This artificial SEI layer can separate the electrode and aqueous electrolyte, thus suppressing Mn dissolution and the Jahn-Teller effect of LiMn2O4. Electrochemical analyses also suggest it may work as the Li+ conductor/reservoir to improve the Li+ diffusion coefficient of the electrode. Consequently, as the cathode of ALIBs, LiPAA@LiMn2O4 harvests a high capacity of 119 mA h g-1 at 0.6C, high rate capability (70 mA h g-1 at 12C), better durability (85.5%@100 cycles) and superior overcharge resistance.Gene therapy is deemed to be a powerful and promising tool to treat many stubborn diseases in the near future. For successful gene therapy, gene vectors play a vital role as they determine whether the edited gene can be loaded and transferred into target cells effectively. However, traditional gene vectors face some serious challenges, especially in biosafety and trans-membrane efficiency. Recently, inspired by cell-penetrating peptides (CPPs) possessing excellent biosafety and trans-membrane efficiency, various types of arginine-based gene delivery systems have been designed and fabricated. In this review, the superiority and mechanism of action of arginine in promoting membrane penetration are briefly presented. Then, four types of arginine-based gene vectors, namely, typical linear polymers, dendrimers, lipids and arginine-based composite gene vectors and their applications are discussed in detail. Finally, the current challenges and future perspectives of arginine-based gene delivery systems are discussed.In this paper, we predict that the tetragonal MnSi and MnC0.5Si0.5 monolayers are mechanically stable metallic ferromagnetic materials. The thermal stability of the MnC0.5Si0.5 monolayer is verified by our ab initio molecular dynamics (AIMD) result at 300 K. Both MnSi and MnC0.5Si0.5 monolayers exhibit room temperature half-metallic properties, which is very promising for spintronic applications. Both monolayers exhibit large perpendicular magnetic anisotropy, which is desirable for maintaining magnetic order and for high density storage spintronics. A bilayer of the MnSi nanosheet has obviously enhanced thermal stability and exhibits antiferromagnetic metal properties. The Néel temperature could be effectively manipulated and improved by surface functionalization. In addition, monolayer and bilayer MnSi nanosheets exhibit nodal lines in the reciprocal space, and the nodal lines are robust against spin orbit coupling.Viral epidemics or pandemics of acute respiratory infections, like influenza or severe acute respiratory syndrome pose a global threat. Antiviral drugs and vaccination may be insufficient to prevent their spread. Therefore, a Cochrane systematic review evaluated effectiveness of physical interventions to interrupt or reduce the spread of respiratory viruses.Introduction Temporomandibular dysfunction (TMD) is caused by multiple factors such as depression, which is characterized by a state of deep sadness, dejection and unhappiness that can be transitory or permanent. Both of these disorders can occur in adolescence, when guidelines are created for what the person will be like in adulthood for the psychological, emotional and anatomophysiological aspects. The objective of this study was to determine the relationship between the degrees of DTM and depression in adolescents of Mayan ancestry from the community of Yobain, Yucatan, Mexico. Methods A correlational and transversal study was conducted, using the Helkimo index and the Beck depression scale, in which 210 adolescents aged 10 to 19 years of Mayan descent were included. 5-FU ic50 Descriptive and inferential statistics were used. Results Some degree of DTM was observed in 74.3% of the participants, and some degree of depression in 51.9%. A higher degree of DTM was associated with a greater degree of depression. The frequency of DTM was similar for both categories of adolescence early and late. However, a higher frequency of severe depression was observed in early adolescence. Conclusions In the absence of other similar studies, a precedent was set with this study on the state of psychological and dental health in this population of Yucatan origin. Also, a guideline was established for referral to other areas of health care, such as psychiatry, neurology and neuropsychiatry.Background Weeksella virosa is one of the two species of the genus Weeksella. Clinical disease due to this bacterium in humans is rare, for which only nine cases have been reported in the literature. Case report A 4-year-old male patient was diagnosed with a left orbit rhabdomyosarcoma Stage III and was admitted to a northeast third level referral center in Mexico. Aerobic, non-pigmented, Gram-negative rod was isolated from a blood culture. W. virosa was identified by Sensititre™ ARIS. This organism has been described in cases of spontaneous bacterial peritonitis, sepsis, pneumonia, ventriculitis, and urinary tract infection. Conclusions Clinicians should consider the diagnosis of W. virosa bacteremia in cases involving immunocompromised patients with oral lesions, although it is infrequent. To the best of our knowledge, this is the first clinical report of W. virosa bacteremia described in an immunocompromised pediatric patient.Background Transient pigmentary lines of the newborn are uncommon cutaneous lesions of unknown etiology. To date, only a few cases have been described. Case report A patient with a combination of transient pigmentary lines and ocular malformation is described. Molecular analysis of the SRY-box 2 (SOX2) and MIFT genes was conducted to rule out any monogenetic etiology. Conclusions Worldwide, this is the eighth case of transient pigmentary lines of the newborn reported, and the first associated with anophthalmia. No mutations in the analyzed genes (SOX2 and MIFT) were identified. Therefore, somatic mutations could be responsible for this anomaly.
