In silico analysis of echinocandins binding to the main proteases of coronaviruses PEDV (3CL) and SARS-CoV-2 (M).

In Silico Pharmacol 2021 1;9(1):41. Epub 2021 Jul 1.

OncoWitan, 59290 Lille, Wasquehal France.

The porcine epidemic diarrhea virus (PEDV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are two highly pathogenic viruses causing tremendous damages to the swine and human populations, respectively. Vaccines are available to prevent contamination and to limit dissemination of these two coronaviruses, but efficient and widely affordable treatments are needed. Recently, four natural products targeting the 3C-like protease (3CL) of PEDV and inhibiting replication of the virus in vitro have been identified: tomatidine, epigallocatechin-3-gallate, buddlejasaponin IVb and pneumocandin B0.

Legionella pneumophila LegC7 effector protein drives aberrant endoplasmic reticulum:endosome contacts in yeast.

Traffic 2021 08 7;22(8):284-302. Epub 2021 Jul 7.

Department of Microbiology, University of Georgia, Athens, Georgia, USA.

Legionella pneumophila is a facultative intracellular bacterial pathogen, causing the severe form of pneumonia known as Legionnaires' disease. Legionella actively alters host organelle trafficking through the activities of "effector" proteins secreted via a type-IVB secretion system, in order to construct the bacteria-laden Legionella-containing vacuole (LCV) and prevent lysosomal degradation. The LCV is created with membrane derived from host endoplasmic reticulum (ER), secretory vesicles and phagosomes, although the precise molecular mechanisms that drive its synthesis remain poorly understood.

Complete disease remission in a and co-mutated brain oligometastatic lung cancer patient after immuno-chemotherapy and surgical resection: a case report.

Transl Lung Cancer Res 2021 May;10(5):2298-2305

Department of Lung Cancer Surgery, Tianjin Medical University General Hospital, Tianjin, China.

Lung cancer is the most common primary malignancy and tends to metastasize to the brain. A multimodal approach, including systematic therapy (targeted therapy, chemotherapy, immunotherapy) and local consolidative therapy (surgical intervention, radiation therapy, ablation therapy), is essential for treatment of oligometastatic lung cancer. The systemic immunotherapy has been shown to increase response rate and survival, which then has the potential benefit of making localized treatment more feasible for some cases of oligometastatic cancer.

Division of Biochemistry, Department of Chemistry, University of Crete, GR-71003, Voutes, Greece. Electronic address:

Coxiella burnetii, the causative agent of Q fever, is an intracellular bacterial pathogen. Studies on Coxiella have shown that a type IVB secretion system (T4BSS) contributes to the establishment of the infection by transferring protein molecules. In this report, we focus on two core proteins of the Coxiella T4BSS, namely the IcmG/DotF protein (CBU_1626) and the IcmK/DotH protein (CBU_1628). Read More

Small 2021 Jun 13;17(24):e2100776. Epub 2021 May 13.

Institute of Materials Science, TU Darmstadt, 64287, Darmstadt, Germany.

Here, the authors performed density functional theory calculations to study the catalytic performance of the nitric oxide reduction reaction (NORR) via a series of transition metal borides (MBenes). This work screened the M B type MBenes from the IVB to V transition metals from the periodic table and systematically probed the catalytic activity and selectivity for the NORR process. It has been reported that Fe B , Mn B , and Rh B can be high-performance catalysts for converting NO to NH with smaller limiting potentials than other MBenes, and Nb B and Hf B have low limiting potentials of -0.

Type A thymoma with simultaneous solitary intrapulmonary metastasis: A case report.

Thorac Cancer 2021 06 7;12(12):1923-1926. Epub 2021 May 7.

Department of Oncology, Immunology and Surgery, Nagoya City University Graduate School of Medical Sciences, Nagoya, Japan.

A 79-year-old woman was referred to our facility because of an abnormal chest shadow. Chest computed tomography (CT) showed a solitary right middle lung nodule with a maximum diameter of 3 mm and anterior mediastinal nodule with a maximum diameter of 21 mm. The lung nodule was suspected of being a primary lung cancer rather than a metastatic tumor because there were no primary malignant tumors, apart from an anterior mediastinal tumor visible on diagnostic imaging, including F fluorodeoxyglucose-positron emission tomography, and a solitary lung nodule.

Pharmgenomics Pers Med 2021 17;14:349-358. Epub 2021 Mar 17.

Department of Medical Genetics, Clinical Emergency Hospital for Children, Cluj-Napoca, Romania.

Introduction: Articular and bone damage, which is so disabling in Mucopolysaccharidosis (MPS), requires attention as to the explanatory bias of the pathogenetic mechanisms identified to date. The vitamin D receptor (VDR) has been investigated in many studies in correlation with bone metabolism, osteoporosis, and the impaired bone mineral density associated with certain polymorphisms of the VDR gene.

The role of maternal effects on offspring performance in familiar and novel environments.

Heredity (Edinb) 2021 Jul 6;127(1):52-65. Epub 2021 Apr 6.

Division of Ecology & Evolution, Research School of Biology, The Australian National University, Canberra, ACT, Australia.

Maternal effects are an important evolutionary force that may either facilitate adaptation to a new environment or buffer against unfavourable conditions. The degree of variation in traits expressed by siblings from different mothers is often sensitive to environmental conditions. This could generate a Maternal-by-Environment interaction (M × E) that inflates estimates of Genotype-by-Environment effects (G × E). Read More

Orbital Design of Two-Dimensional Transition-Metal Peroxide Kagome Crystals with Anionogenic Dirac Half-Metallicity.

J Phys Chem Lett 2021 Apr 2;12(14):3528-3534. Epub 2021 Apr 2.

Hefei National Laboratory for Physical Sciences at the Microscale, CAS Key Laboratory of Materials for Energy Conversion, CAS Center for Excellence in Nanoscience, and School of Chemistry and Materials Sciences, University of Science and Technology of China, Hefei, Anhui 230026, China.

Assembling p orbital ferromagnetic half-metallicity and a topological element, such as a Dirac point at the Fermi level, in a single nanomaterial is of particular interest for long-distance, high-speed, and spin-coherent transportation in nanoscale spintronic devices. On the basis of the tight-binding model, we present an orbital design of a two-dimensional (2D) anionogenic Dirac half-metal (ADHM) by patterning cations with empty d orbitals and anions with partially filled p-type orbitals into a kagome lattice. Our first-principles calculations show that 2D transition-metal peroxides TM(O) (TMO, TM = Ti, Zr, Hf), containing group IVB transition-metal cations [TM] bridged with dioxygen anions [O] in a kagome structure, are stable ADHMs with a Curie temperature over 103 K.
