The L-fucose-specific lectin from Aspergillus niger (ANL), isolated from the corneal smears of a keratitis patient was reported earlier. Here, we examined the interaction of ANL with human hepatocellular and colon cancer cells, evaluated its anti-cancer activity and diagnostic potential to detect aberrantly glycosylated tumour-associated serum glycoproteins such as alpha-fetoprotein (AFP). We observed that ANL strongly bound to both HepG2 and HT-29 cell-lines and this interaction was effectively blocked with L-fucose and mucin in a dose and time-dependent manner with an IC50 of 1.25 and 5 μg/mL for HepG2 and HT-29 cells respectively at 48 hours. ANL treatment increased hypodiploidy and decreased the number of HepG2 cell in G0 -G1 phase at both 24 and 48 hours. Furthermore, ANL increased the level of apoptosis in both HepG2 and HT-29 cells in a time-dependent manner via enhanced production of reactive oxygen species and altered mitochondrial membrane potential, indicative of intrinsic apoptotis pathway activation. Immunoblot analysis confirmed the time-dependent elevation of levels of cytochrome c, initiator caspase-9 and activation of caspase-3. ANL immunohistochemistry on colon cancer tissue and quantification of AFP in HCC patient serum samples by developing an ANL-anti-AFP antibody sandwich enzyme-linked immunosorbent assay confirmed the diagnostic potential of ANL. Here, interaction of ANL with AFP could be effectively blocked in the presence of competing fucose-bearing glycans. We found ANL to be more sensitive than Lens culinaris lectin, a well-known fucose-specific lectin and currently used diagnostic agent. ANL can be further explored as a diagnostic and anti-cancer agent.Surgical site infection in the presence of orthopedic implants poses significant healthcare and socioeconomic burden. selleck kinase inhibitor To assess the potential of various prevention strategies against Staphylococcus-induced stainless steel-associated infections, a review of animal evidence was designed. The databases of PubMed, Embase, and CENTRAL were searched until March 10, 2020, for articles including animal models with stainless steel instrumentation and techniques to prevent Staphylococcus infection. We conducted a random-effects meta-analysis of standardized mean differences (SMD) with subgroup analysis linked to various protection strategies and we recorded complications. Quality was assessed with the SYRCLE's risk of bias tool. Twenty-five studies were included. Combined active coating (featuring organic antibacterial compound release) and degradable passive finishing (lipid- or polymer-based structure modification reducing bacterial adhesion) was favored over untreated controls (SMDs for methicillin-sensitive Staphylococcus aureus [MSSA] and methicillin-resistant Staphylococcus aureus [MRSA] were -3.46, 95% CI [-4.53 to -2.4], p  less then  .001 [n = 4 head-to-head comparisons]; and -6.67, 95% CI [-10.53 to -3], p  less then  .001 [n = 5 head-to-head comparisons], respectively). Systemic vitamin D supplementation and systemic antibiotic administration with or without local antibiotics demonstrated favorable outcomes against MSSA infection. On the contrary, no benefit was seen following vaccination. Of note, no side effects were documented. On the basis of data gathered from eight studies, which comprised 294 animals, a bioresorbable polymer- or lipid-based surface modification supplemented with organic coating yielded improved infection-related outcomes against MSSA and MRSA stainless steel infections, and therefore, this strategy could be further investigated in human research.With the rapid development of nanotechnology, new nanomaterials with enormous potentials continue to emerge, especially metal nanomaterials. Metal nanomaterials possess the characteristics of metals and nanomaterials, so they are widely used in many fields. But at the same time, whether the use or release of metal nanomaterials into the environment is toxic to human beings and animals has now attained widespread attention at home and abroad. Currently, it is an indisputable fact that cancer ranks among the top causes of death among residents worldwide. The properties of causing DNA damage and mutations possessed by these metal nanomaterials make them unpredictable influences in the body, subsequently leading to genotoxicity and carcinogenicity. Due to the increasing evidence of their roles in carcinogenicity, this article reviews the toxicological and carcinogenic effects of metal nanomaterials, including nano-metal elements (nickel nanoparticles, silver nanoparticles, and cobalt nanoparticles) and nano-metal oxides (titanium dioxide nanoparticles, silica nanoparticles, zinc oxide nanoparticles, and alumina nanoparticles). This article provides a reference for the researchers and policymakers to use metal nanomaterials rationally in modern industries and biomedicine.
Technological advances in medicine have brought about many novel skin imaging devices. This review aims to evaluate the scientific evidence supporting the use of noninvasive optical imaging techniques to aid in the diagnosis and prognosis of inflammatory skin diseases.

PubMed and Scopus were searched in September 2020 according to PRISMA guidelines for articles using reflectance confocal microscopy (RCM), optical coherence tomography (OCT), and multiphoton microscopy (MPM) in inflammatory skin diseases, excluding studies monitoring treatment efficacy.

At the time of the study, there were 66 articles that addressed the utilization of noninvasive imaging in interface, spongiotic, psoriasiform, vesiculobullous, and fibrosing/sclerosing inflammatory skin dermatoses RCM was utilized in 46, OCT in 16, and MPM in 5 articles. RCM was most investigated in psoriasiform dermatoses, whereas OCT and MPM were both most investigated in spongiotic dermatoses, including atopic dermatitis and allergic contact dermatitis.

There is preliminary evidence to support the diagnostic potential of noninvasive optical imaging techniques in inflammatory skin diseases. Improvements in the devices and further correlation with histology will help broaden their utility. Additional studies are needed to determine the parameters for diagnostic features, disease differentiation, and staging of inflammatory skin conditions. Lasers Surg.
