Chitosan-carrageenan microbeads containing nano-encapsulated curcumin: Nano-in-micro hydrogels as alternative-therapeutics for resistant pathogens associated with chronic wounds.

Antimicrobial resistance is an issue of global relevance for the treatment of chronic wound infections. In this study, nano-in-micro hydrogels (microbeads) of chitosan and κ-carrageenan (CCMBs) containing curcumin-loaded rhamnosomes (Cur-R) were developed. The potential of Cur-R-CCMBs for improving the antibacterial activity and sustained release of curcumin was evaluated.

Proteosomes based on milk phospholipids and proteins to enhance the stability and bioaccessibility of β-carotene.

Proteosomes (P) based on milk fat globule membrane's phospholipids (MPs), whey protein isolate (WPI) and sodium caseinate (CasNa) were developed by ultrasonication to encapsulate β-carotene. Entirely milk-ingredients based proteosomes (WPI-MPs-P and CasNa-MPs-P) revealed homogenous distribution with size diameters < 250 nm. WPI-MPs-P depicted positive ζ-potential values (+15.

Active Composite Packaging Reinforced with Nisin-Loaded Nano-Vesicles for Extended Shelf Life of Chicken Breast Filets and Cheese Slices.

Unlabelled: To meet the demands for more effective and ecofriendly food packaging strategies, the potential of nisin-loaded rhamnolipid functionalized nanofillers (rhamnosomes) has been explored after embedding in hydroxypropyl-methylcellulose (HPMC) and κ-carrageenan (κ-CR)-based packaging films. It was observed that intrinsically active rhamnosomes based nanofillers greatly improved the mechanical and optical properties of nano-active packaging (NAP) films. Incorporation of rhamnosomes resulted in higher tensile strength (5.

Chitosan-curcumin complexation to develop functionalized nanosystems with enhanced antimicrobial activity against hetero-resistant gastric pathogen.

With the apparent stagnation in the antibiotic discovery and the propagation of multidrug resistance, Helicobacter pylori associated gastric infections are hard to eradicate. In pursuance of alternative medicines, in this study, covalent modification of chitosan (CS) polymer with curcumin (Cur) was accomplished. Proton Nuclear Magnetic Resonance and Fourier Transform Infrared spectroscopy elucidated the covalent interaction between Cur and CS with characteristic peak of imine functional group (C=N).

Elucidating the Photoluminescence Quenching in Ensulizole: an Artificial Water Soluble Sunscreen.

Employing natural or artificial sunscreens is essential to protect the skin from ultraviolet radiations that cause premature aging and develop melanoma and other forms of skin cancer. The 2-Phenylbenzimidazole-5-sulfonic acid, commonly known as ensulizole is a water-soluble artificial sunscreen that absorb UV-B (280 nm - 315 nm) radiations and protects the skin against the harmful effects of these radiations. We have measured steady-state photoluminescence (SSPL) spectra and photoluminescence (PL) kinetics of this compound in various conditions.

Bioconjugate synthesis, phytochemical analysis, and optical activity of NiFeO nanoparticles for the removal of ciprofloxacin and Congo red from water.

In this paper, Jr.NiFeO nanoparticles (NPs) were synthesized first time using the leaves extract of Juglans regia via a straightforward process. The physio and phytochemical analysis of plant confirm the presence of macromolecules which function as bio-reductant and stabilize the nanoparticles.

Epidemiology of young breast cancer patients at Gujranwala: A single institution based study.

The objective of this study was to illustrate the statistical and medical characteristics of females younger than 40 years presenting with breast cancer at GINUM. A descriptive case series in which 235 patients who fulfilled the inclusion and exclusion criteria were included. The majority of the patients had advanced disease at presentation.

Alginate-caseinate based pH-responsive nano-coacervates to combat resistant bacterial biofilms in oral cavity.

Biofilm associated microbial resistance is a major concern in oral health and hygiene. Nano-antimicrobials (NAMs) having natural antibiotic replacers e.g.

Chitosan-albumin based core shell-corona nano-antimicrobials to eradicate resistant gastric pathogen.

In this study, protein/polysaccharide core-shell-corona (PP-CSC) nano delivery systems (NDS) were prepared by using bovine serum albumin (BSA) and chitosan (CS). The potential of PP-CSC-NDS for increasing the stability and bio-accessibility of ε-poly-l-lysine (ε-PL) as effective therapy for gastric Helicobacter pylori was investigated. The presence of CS-shell increased the size (223 ± 1.

Primary Mammary Small Cell Carcinoma.

Neuroendocrine breast cancer was defined in 2003 by WHO as a separate and unique breast cancer subtype. Primary small cell carcinoma of the breast, an exceptionally uncommon and aggressive tumor, is frequently characterised by early progression and worse outcome. Moreover, it is essential to distinguish between small cell carcinoma arising primarily in the breast and the metastatic disease to the breast.

Polyelectrolyte Multicomponent Colloidosomes Loaded with Nisin Z for Enhanced Antimicrobial Activity against Foodborne Resistant Pathogens.

Food grade micro- or nano-carrier systems (NCS) are being developed to improve the controlled release of antimicrobial agents. To augment the stability of liposomal NCS and to overcome the limitations associated with the use of free bacteriocin (nisin) in the food system, multi-component colloidosomes (MCCS) were developed by electrostatic interactions between anionic alginate and cationic chitosan (multilayer) around phospholipids based liposomes (core). Zeta-sizer results revealed the average diameter of 145 ± 2 nm, 596 ± 3 nm, and 643 ± 5 nm for nano-liposome (NL), chitosomes (chitosan coated NL) and MCCS, respectively.

Chronic non puerperal uterine inversion secondary to sub-mucosal fibroid.

Inversion of uterus is a rare clinical condition, if not associated with puerperium or third stage of labour. Non-puerperal uterine inversion usually results secondary to tumour implanted at fundus of the uterus. An unusual case of non-puerperal uterine inversion caused by a large submucosal fundal fibroid is reported where a 39-year-old woman presented with heavy bleeding per vaginum and profuse vaginal discharge.

Synthesis, morphology, and properties of self-assembled nanostructured aramid and polystyrene blends.

Aramid (Ar), produced from the reaction of aromatic diamines and diacid chloride, was reactively compatibilized with amino-functionalized polystyrene (APS) to explore blend morphology and interfacial cohesion. Two blend systems, Ar/PS and Ar/APS, were investigated over a range of pristine polystyrene (PS) or modified APS ratios. Morphology and thermal and mechanical properties were probed to evaluate the effect of amine units of APS on the compatibility with Ar.
