Abstract
Gemcitabine is a nucleoside analog effective against a number of cancers. However, it has an oral bioavailability of less than 10%, due to its high hydrophilicity and low permeability through the intestinal epithelium. Therefore, the aim of this project was to develop a novel nanoparticulate drug delivery system for the oral delivery of gemcitabine to improve its oral bioavailability. In this study, gemcitabine-loaded β-glucan NPs were fabricated using a film-casting method followed by a freezer-milling technique. As a result, the NPs showed a small particle size of 447.6 ± 14.2 nm, and a high drug entrapment efficiency of 64.3 ± 2.1%. By encapsulating gemcitabine into β-glucan NPs, a sustained drug release profile was obtained, and the anomalous diffusion release mechanism was analyzed, indicating that the drug release was governed by diffusion through the NP matrix as well as matrix erosion. The drug-loaded NPs had a greater ex vivo drug permeation through the porcine intestinal epithelial membrane compared to the plain drug solution. Cytotoxicity studies showed a safety profile of the β-glucan polymers, and the IC50s of drug solution and drug-loaded β-glucan NPs were calculated as 228.8 ± 31.2 ng·mL-1 and 306.1 ± 46.3 ng·mL-1, respectively. Additionally, the LD50 of BALB/c nude mice was determined as 204.17 mg/kg in the acute toxicity studies. Notably, pharmacokinetic studies showed that drug-loaded β-glucan NPs could achieve a 7.4-fold longer T1/2 and a 5.1-fold increase in oral bioavailability compared with plain drug solution. Finally, in vivo pharmacodynamic studies showed the promising capability of gemcitabine-loaded β-glucan NPs to inhibit the 4T1 breast tumor growth, with a 3.04- and 1.74-fold reduction compared to the untreated control and drug solution groups, respectively. In conclusion, the presented freezer-milled β-glucan NP system is a suitable drug delivery method for the oral delivery of gemcitabine and demonstrates a promising potential platform for oral chemotherapy.

Abstract
Aim One in eight fatalities globally are considered cancer-related. The need for cancer therapy is growing. Natural products continue to play a role in drug development, as up to 50% of authorized drugs in the last 30 years have been isolated from natural sources. Methods Anticancer, antioxidant, antibacterial, antifungal, antiviral, analgesic, anti-inflammatory, and other actions have all been reported in research papers using plants from the Syzygium genus in the treatment and prevention of disease. Results Results from the anticancer test showed that the genus, especially Syzygium aqueum, Syzygium samarangense, and Syzygium cumini had significant promise as an anticancer agent in vitro against several cancer cell lines. Numerous factors, including phytochemical composition, increased apoptotic activity, decreased cell proliferation, stopped angiogenesis, and reduced inflammation. Conclusions These results, despite preliminary, show promise for further purification and investigation of bioactive compounds and extracts within the genus Syzygium for their anticancer properties.

Abstract
Abstract
Background
Nowadays, researchers are moving toward a herbal approach to cancer treatment because of the harmful effects of synthetic anti-tumor drugs. The evaluation of active compounds with plant origin may help in the remedy of human illnesses in the future. These active compounds have direct or indirect curative efficacies on difficult to cure diseases such as cancer. Investigation of nanoforms of these active compounds is one of the curious topics of the scientific community.
Main body
Saffron and its components obtained from Crocus sativa, essential oils obtained from lavender, Syzygium aromaticum called cloves and Beta vulgaris are known for their anticancer effects. Nano-drugs are designed to increase the anticancer activity of plant-derived drugs. Herbal extracts operate very great in the production of nanoparticles. The aim is to ensure that only the nano-drug is delivered to the tumor site. Furthermore, nanoparticles have hazardous effects when analyzed at elevated doses, but this issue can be doped together with plant extracts.
Short conclusions
The nanocomposites (graphene oxide, solid lipid nano and nanoemulsion) of phytomolecules obtained from saffron, clove, lavender and red beet may be effective in minimizing these toxic effects. In the near future, detecting the anticancer molecular mechanisms of these naturally derived compounds and nanocomposites could contribute to further cancer research. Apart from these, these compounds and its nanocomposites could have antiviral effects against today's threat covid-19 virus. Consequently, more promising anticancer and antiviral agents would be discovered.

Abstract
N-trimethyl chitosan (TMC) is a multifunctional polymer that can be used in various nanoparticle forms in the pharmaceutical, nutraceutical and biomedical fields. In this study, TMC was used as a mucoadhesive adjuvant to enhance the oral bioavailability and hence antitumour effects of gemcitabine formulated into nanocomplexes composed of poly(lactic-co-glycolic acid) nanoparticles (PLGA NPs) conjugated with d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS). A central composite design was applied to achieve the optimal formulation. Cellular uptake and drug transportation studies revealed the nanocomplexes permeate over the intestinal cells via adsorptive-mediated and caveolae-mediated endocytosis. Pharmacokinetic studies demonstrated the oral drug bioavailability of the nanocomplexes was increased 5.1-fold compared with drug solution. In pharmacodynamic studies, the formulation reduced tumour size 3.1-fold compared with the drug solution. The data demonstrates that TMC modified nanocomplexes can enhance gemcitabine oral bioavailability and promote the anticancer efficacy.

Abstract
Gemcitabine is a nucleoside analogue effective against a number of cancers. However, the full potential of this drug has not been realised, in part due to low oral bioavailability and frequent dosing requirements. This study reports the synthesis, in-vitro, ex-vivo and in-vivo evaluation of trimethyl chitosan (TMC) - CSKSSDYQC (CSK) peptide conjugates capable of enhancing the oral bioavailability of gemcitabine due to the ability to target intestinal goblet cells and promote intestinal cellular uptake. TMC was synthesized by a novel two-step methylation method to improve quanternization and yield. The CSK-TMC conjugates were prepared by ionic gelation to achieve particles sized at 173.6 ± 6.8 nm, zeta potential of +18.5 ± 0.2 mV and entrapment efficiency of 66.4 ± 0.1%, capable of sustained drug release. By encapsulating gemcitabine into CSK-TMC conjugates, an increased amount of drug permeated through porcine intestinal epithelial membranes compared with the unconjugated TMC nanoparticles (NPs). The rate of cellular uptake of drug loaded conjugates into HT29-MTX-E12 intestinal goblet cells, was time- and concentration-dependant. The conjugates underwent active transport associated with adsorptive mediated, clathrin and caveolae mediated endocytosis. In cellular transport studies, drug loaded conjugates had greater drug transport capability compared with drug solution and TMC NPs over the co-cultured Caco-2/HT29-MTX-E12 cell monolayer. The drug loaded conjugates exhibited electrostatic interaction with the intestinal epithelial cells. Both P-glycoprotein (P-gp) and multiple resistance protein-2 (MRP2) efflux affected the cellular transport of the conjugates. Importantly, during the pharmacokinetic studies, the orally administrated drug loaded into TMC NPs showed an improved oral bioavailability of 54.0%, compared with gemcitabine solution of 9.9%. Notable, the CSK-TMC conjugates further improved oral bioavailability to 60.1% and reduced the tumour growth rate in a BALB/c nude mouse model, with a 5.1-fold and 3.3-fold reduction compare with the non-treated group and gemcitabine solution group. Furthermore, no major evidence of toxicity was discernible on histologic studies of selected organs. In conclusion, the presented CSK-TMC conjugates and TMC nanoparticles both significantly improve the oral bioavailability of gemcitabine and have the potential for the treatment of breast cancer.

Abstract
Recently, it is hypothesized that there might be an association between immunological disorders and cervical premalignant and malignant abnormalities. Related studies have been generally focused on some particular autoimmune disease, specially the Systemic Lupus Erythematosus (SLE). This study aimed at comparing the rate of Pap smear abnormalities in female patients with autoimmune diseases and normal counterparts. In a case-control setting, 118 female patients with various autoimmune diseases (the case group) and 118 healthy female counterparts (the control group) were recruited in Tabriz Imam Reza Teaching Centre in a 24 months period of time. The two groups were matched for demographics and known risk factors of cervical malignancy. Frequencies of abnormal Pap smear testing were compared between the two groups. The autoimmune disorders were SLE (74 patients), rheumatoid arthritis or RA (32 patients), systcmic sclerosis or SS (7 patients) and ankylosing spondylitis or AS (5 patients) in the case group. Frequency of abnormal Pap smear testing was significantly higher in the case group comparing with that in the controls (7.6% vs. 1.7%; p = 0.03). Frequency of abnormal Pap smear testing was higher in the patients with SLE (8.1%) and RA (9.3%) comparing with that in the controls; However, these differences were marginally nonsignificant (p = 0.06 and p = 0.07, respectively). Frequency of cases with abnormal Pap smear testing was not statistically different between the autoimmune disorders (p = 0.99). Based on these findings and in conclusion, there might be an association between the autoimmune disorders and occurrence of premalignant or malignant lesions in cervix. Further studies with larger samples sizes are recommended.
