The drug is photo and thermal sensitive, so the analysis should be done in moderate conditions only.
Introduction: Nosocomial infections are caused by the retrograde spread of viral, bacterial and fungal pathogens from the hospital environment to the patients. Despite the efforts to avoid cross-infection in the dental office using sterilized instruments, individual protection equipment, and disinfection procedures, there is an increased risk of cross-infection through dental units, since one dental chair is used to treat many patients. Materials and methods: Seven strains of micro-organisms- Streptococcus, Lactobacillus, Pseudomonas aeruginosa, Klebsiella, Enterococcus, Staphylococcus aureus, Candida albicans, E. coli, and Legionella were taken. Neem extract, Aloe Vera Juice, and 0.2% chlorhexidine were tested against all these organisms. Sterile discs were incorporated with an equal amount of prepared formulations using a micropipette. Then these discs were placed equidistant to each other following which these plates were incubated for 24 hours. Results: Zone of inhibition was higher in chlorhexidine 12mm, 22mm, 11mm, 8mm, 18mm, 12mm, 11mm, 14mm and 15 mm followed by neem extract 7mm, no inhibition, 10mm, 7mm, 11mm, 7mm, 11mm and 9 mm and no inhibition by Aloe Vera juice against Streptococcus, Lactobacillus, Pseudomonas aeruginosa, Klebsiella, Enterococcus, Staphylococcus Aureus, Candida albicans, E.coli and Legionella respectively. Conclusion: Results from this study have shown that chlorhexidine was most effective against dental unit waterline pathogens followed by neem extract and least by Aloe Vera juice.

The main objective of this work is to determine the effect of the harvest period on the yield and chemical quality of the essential oils of the Eucalyptus sideroxylon A. Cunn. leaves of the Mamora forest, Dayet Zerzour Bnifdel region, Rabat. Essential oil yields are remarkably high above 2.3%, with an ultimate rate of 5.48% for the month of April. The chemical quality of these essential oils is characterized by the presence of two major monoterpenes, 1,8-cineole (eucalyptol) and α-terpineol, which are proportionally inverted in terms of quantity. During the wet months between September and March, the cineole predominates with levels ranging from 72.67% to 86.11% and the other dry months are characterized by an increase of α-terpineol rate from 12.05% to 25.61%. This inverted chemical variability reveals a change in the orientation of cineole and α-terpineol biosynthesis under the control of climatic factors. This work allows us to discern favorable periods for the harvest of Eucalyptus sideroxylon leaves in terms of yield and quality of essential oils.
Triple-negative breast cancer (TNBC) remains as the deadliest cancer type due to the lack of treatment options. Hence, several attempts have been made to develop new anticancer for TNBC therapy. This study intended to challenge curcumin analog (CCA)-1.1, which is derived from pentagamavunone-1 structure, against the 4T1 cell line and TNBC cell model, covering the cytotoxic activity in correlation with cell cycle progression, apoptosis induction, reactive oxygen species (ROS) generation, and senescence evidence. The cell viability, cell cycle profile, apoptosis induction, intracellular ROS level, and senescence induction were determined in vitro using trypan blue exclusion, propidium iodide (PI) staining, Annexin-PI staining, dichlorofluorescein diacetate staining, and senescence-associated-β-gal method. CCA-1.1 showed cytotoxic activity on 4T1 cells, giving half maximal inhibitory concentration value of 3M, but was less toxic on non-cancerous 3T3-L1 cells. CCA-1.1 induced rapid cell death and inhibited cell cycle progression at the mitotic phase. Instead, of causing apoptosis, CCA-1.1 induced mitotic catastrophe. Furthermore, CCA-1.1 itself increased the intracellular ROS level and induced senescence, possibly through catastrophic cell death. Altogether, our preliminary study strengthens the potency of CCA-1.1 for its anticancer activities against TNBC cells and prospective to be pharmaceutically developed as a novel candidate for cancer therapy.

Background: Lornoxicam is an important non-steroidal anti-inflammatory agent. It is practically insoluble in water leading to difficulty in formulation and adversely affecting its pharmacokinetic and pharmacodynamic properties. For drugs like lornoxicam, the rate of absorption is often controlled by the rate of dissolution. Thus the enhancement of the dissolution rate and in turn solubility of poorly soluble drugs is important. Aims: The purpose of this present study was to prepare binary and ternary systems with lornoxicam, carrier and surfactant. Materials and Methods: Binary solid dispersions of lornoxicam with Gelucire 50/13were prepared at different drug to carrier ratios(1:1), (1:3), and (1:5). Polysorbate 80, a nonionic surfactant, was incorporated as a third component to obtain the ternary solid dispersion system. The solubilizing and absorption enhancer properties of this ternary solid dispersion system was then investigated. Solid systems were prepared by mixing or co precipitation and were characterized by different scanning calorimetery, X- ray diffractometery followed by tests for dissolution behavior. Results: The results thus obtained showed a remarkably improved dissolution of drug from the ternary solid dispersion systems when compared with the binary solid dispersion systems. In order to verify the improved dissolution therapeutically, a paw edema test for the formulation was carried in rats where in the ternary system exhibited a potent local anti-inflammatory activity against carrageenan induced paw edema when compared to pure drug. Thus vindicating the solubilizing and dissolution enhancing effect due to the addition of third additive to the binary system of lornoxicam. Conclusions: The drug loaded lornoxicam binary solid dispersion with GL50/13 exhibited faster dissolution rate than drug alone. The significant high drugdissolution rate was obtained in a ternary solid dispersion system using tween 80 as a third component. The fastest drug dissolution obtained was in the ratio of 1:5:1 w/w/w (LOR /GL50/13/ tween 80). The in vivo experimental results corroborated the in vitro outcomes of lornoxicam.
The current therapy for patients with thyroid cancer is total or near to total thyroidectomy with Radio Iodine treatment. Subsequent to the thyroidectomy the patients are on Levothyroxine as a supplement therapy to maintain the Thyroid hormone levels.Levothyroxine has been considered as a narrow therapeutic index drug. In Thyroid cancer patients, radio-iodine ablation procedure causes hypothyroid state which will be further elongated by the administration of sub optimal doses and hyperthyroid symptoms with higher doses. The current study was conducted to evaluate the covariates influencing the drug concentration of levothyroxine in our target population, i.e Patient with Papillary carcinoma, undergone total thyroidectomy followed by¹³¹I ablation and on Levothyroxine.

We investigated the antihyperlipidemic activity of Strychnos potatorum seeds. The current study was undertaken to assess the hypolipidemic, hypocholesterolemic and hypotriglyceridemic potential of the seeds using triton WR-1339 (Tyloxapol) induced hyperlipidemia in rats. The animals were divided into five groups: control, hyperlipidemic, hyperlipidemic plus Atorvastatin, hyperlipidemic plus Strychnos potatorum seed powder 100mg/kg and Strychnos potatorum seed powder 200mg/kg. Hyperlipidemia was induced by single intraperitoneal injection of triton WR 1339 at a dose of 400mg/kg. Intragastric administration of seed powder significantly (p<0.05) decreased serum total cholesterol, triglycerides, low density lipoprotein cholesterol, very low density lipoprotein cholesterol levels in rats in dose dependent and time dependent manner compared to hyperlipidemic group. Thus, the findings of the investigation suggest that Strychnos potatorum seeds exhibited quite competitive potential when compared with reference drug Atorvastatin against experimentally induced hyperlipidemia.
Dunaliella tertiolecta is a marine microalgae rich in pharmacologically important xanthophyll carotenoid, zeaxanthin. This study demonstrated ultrasound assisted extraction (UAE) of zeaxanthin from D. tertiolecta (NIOT 141). Initially, the solvent type and antioxidant concentration for zeaxanthin extraction were optimized using one-variable-at-a-time (OVAT) experiments. Subsequently, three factors influencing the UAE yield of zeaxanthin like sonication time, sonication temperature and solid (algal biomass): liquid (solvent) ratio were investigated using response surface methodology (RSM). Both identification and quantification of zeaxanthin was done with aid of RP-HPLC (Reverse phase high pressure liquid chromatography). The data obtained from the experimental runs were fitted into a quadratic model. The model for maximizing the zeaxanthin extraction yield from D. tertiolecta had a high coefficient of determination of 0.9801. The optimized parameters for UAE of zeaxanthin from D. tertiolecta were sonication time of 33.6 min, sonication temperature of 59.2oC with a solid –liquid ratio 1:62 (g ml⁻¹) and a predicted zeaxanthin content of 13.42 mg g⁻¹. The optimized UAE process parameters were verified by triplicate validation experiments and a zeaxanthin content of 13.85 ± 0.15 mg g⁻¹ was obtained. This further confirmed the reliability and precision of the RSM design. The zeaxanthin yield obtained in the optimized UAE of zeaxanthin content was 2.2 fold higher than the zeaxanthin content obtained by conventional solvent extraction process (6.24 ± 0.05 mg g⁻¹). Zeaxanthin from D. tertiolecta was purified and characterized using UHPLC-MS. The results indicated that D. tertiolecta can be used as a potential source of zeaxanthin.
