Abstract
Induction of immunogenic cell death (ICD) is a promising strategy for cancer immunotherapy. Chrysin, which has potential anticancer effects, faces limitations in clinical applications due to its poor water solubility. This study aimed to formulate chrysin with PEG-poly(α-benzylcarboxylate-ε-caprolactone) (PBCL) nanoparticles (NPs) and assess their anticancer and ICD-inducing potency in melanoma cells, comparing with free chrysin. The co-solvent evaporation method was employed to develop chrysin-loaded NPs. UV spectroscopy, dynamic light scattering, and the dialysis bag method were used to evaluate the encapsulation efficiency (EE), particle size, polydispersity index (PDI), and drug release profile, respectively. The anticancer effects of the drugs were assessed using the MTT and trypan blue exclusion assays. Flow cytometry was employed to evaluate apoptosis and calreticulin (CRT) expression. ELISA and western blotting were used to detect heat shock protein 90 (HSP90), Annexin A1, GRP78 (Glucose-related protein78), and activated protein kinase R-like endoplasmic reticulum kinase (p-PERK). Chrysin-loaded PEG-PBCL NPs (chrysin-PEG-PBCL) showed an EE of 97 ± 1%. Chrysin-PEG-PBCL was 38.18 ± 3.96 nm in size, with a PDI being 0.62 ± 0.23. Chrysin-PEG-PBCL showed an initial burst release, followed by sustained release over 24 h. Chrysin-PEG-PBCL exhibited a significantly stronger anticancer effect in B16 cells. Chrysin-PEG-PBCL was found to be more potent in inducing apoptosis. Both free chrysin and chrysin NPs induced ICD as indicated by an increase in the levels of ICD biomarkers. Interestingly, chrysin NPs were found to be more potent inducers of ICD than the free drug. These findings demonstrate that chrysin and chrysin-PEG-PBCL NPs can induce ICD in B16 cells. PEG-PBCL NPs significantly enhanced the potency of chrysin in inducing ICD compared to its free form.

Abstract
PURPOSE Triple-negative breast cancer (TNBC) is the most aggressive form of breast cancer, accounting for 20% of cases. Due to the lack of a molecular target, limited options are available for TNBC treatment. Radiation therapy (RT) is a treatment modality for the management of TNBC following surgery; however, it has a detrimental effect on surrounding healthy tissues/cells at a higher rate. METHODS We examined the effect of RT in combination with chrysin as a possible radiosensitizing agent in an MDA-MB-231 cell line as a model of a TNBC. The growth inhibitory effects of chrysin were examined using an MTT assay. Flow cytometry was performed to evaluate apoptosis and expression of hypoxia-induced factor-1α (HIF-1α). The protein expression of p-STAT3/STAT3 and Cyclin D1 was examined using western blotting. Real-time PCR determined apoptotic-related genes (Bax, BCL2, p53). RESULTS Treatment of MDA-MB-231 cells with chrysin in combination with RT caused synergistic antitumor effects, with an optimum combination index (CI) of 0.495. Our results indicated that chrysin synergistically potentiated RT-induced apoptosis in MDA-MB-231 compared with monotherapies (chrysin and/or RT alone). Expression of HIF-1α was decreased in the cells exposed to combinational therapy. The apoptotic effect of combinational therapy was correlated with increased Bax (pro-apoptotic gene) and p53 levels along with reduced expression of Bcl-2 (anti-apoptotic gene). Increased apoptosis was associated with reduced expression of Cyclin D1, p-STAT3. CONCLUSION These findings highlight the potential effect of chrysin as a radiosensitizer, indicating the synergistic anti-cancer effect of chrysin and RT in TNBC. Further investigation is warranted in this regard.

Abstract
Candida species are the commensal organisms of human and animal mucosa that cause a wide range of debilitating diseases in immunocompromised patients and other susceptible individuals. The present study aimed to investigate the ability of clinical isolates of various Candida species to produce proteinase and phospholipase, hydrophobicity and biofilm forming ability that assumed to have a vital role in Candida pathogenicity. Eighty-four Candida strains belonged to Candida albicans (44.1%), C. glabrata (5.9%), C. guilliermondii (5.9%), C. krusei (10.8%), C. parapsilosis (26.2%), and C. tropicalis (7.1%) were examined for proteinase and phospholipase production, cell surface hydrophobicity and biofilm forming ability. The production of proteinase and phospholipase was detected in 81 (96.4%) and 79 (94.1%) of the strains, respectively. C. albicans showed the highest proteinase and phospholipase activity (mean Pz values of 0.42±0.25 and 0.72±0.28) and biofilm formation ability (0.66±0.22). C. parapsilosis had the highest hydrophobicity (42.97±16.1), which showed a good correlation with biofilm formation ability. A considerable percentage of non-albicans Candida strains produced significant amounts of proteinase and phospholipase with a good ability of biofilm formation in vitro. Taken together, our results further substantiated that enzymatic activity, hydrophobicity and the ability for biofilm formation are important virulence factors which may be account for pathogenicity of various Candida species distributed in albicans and non-albicans groups.

Abstract
The current study is aimed at investigation of the opium effects on the apoptosis of different cell lines in culture medium and compares such effects with one another. The study is carried out on over 8 cell lines (AA8, AGS, Hela, HepG2, MCF7, N2a, PC12, WEHI). A 2.86 x 10-4 g/ml opium concentration was prepared and added to the culture medium of the cell lines for 48 hours. Cytotoxicity was tested by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. The apoptotic effect of opium on the cell lines was analyzed by Annexin-PI test. Opium with concentration of 2.86 x 10-4 g/ml in 48 hours significantly induces apoptosis in certain cell lines (i.e. AA8, N2a, WEHI), apoptosis and necrosis in some others (i.e. Hela, HepG2, MCF7, and PC12), and also solely necrosis in the AGS cell line. One could infer that the usage of opium with different levels in different tissues leads to certain disorders in some tissues and may have therapeutic effects under distinctive conditions (i.e. unchecked growth of cells) as confirmed by the results.

Abstract
Polyomavirus BK is an important risk factor for nephropathy and renal lose after kidney transplantation. CXCL9 is a key immunoregulatory molecule which participates in stimulation and migration of immune cells to the infected sites. Thus, the main aim of this study was to evaluate the expression levels of CXCL9 mRNA and serum levels in the infected polyomavirus BK infected renal transplant patients with and without nephropathy compared with healthy controls. This cross sectional study was performed on three studied groups including: polyomavirus BK infected vs. non-infected renal transplant patients with nephropathy and healthy controls. The mRNA and serum levels of CXCL9 were evaluated on the studied patient and control samples using an in-house comparative real time PCR and ELISA methods, respectively. The mRNA expression and serum levels of CXCL9 were both increased in polyomavirus BK infected compared with non-infected renal transplant patients and also in comparing with healthy controls. This upregulation was significant in the serum level in polyomavirus BK infected vs. non-infected patients and also in comparing with controls. According to these results, polyomavirus BK can induce renal complications via stimulation of inflammatory biomarkers like chemokine. Confirmation of the increasing of the expression and production of CXCL9 as a pro-inflammatory chemokine in renal transplanted polyomavirus BK infected patients with nephropathy need to confirm in further completed studies with longer follow-up.

Abstract
BACKGROUND/AIMS The present study examined the preventive effect of ginger against renal ischemia-reperfusion (I-R) injury. METHODS 30 adult male rats were used. The animals were allocated to five groups of 6 rats: (1) normal (N), (2) normal + ginger (N+G), (3) right nephrectomy (Sham), (4) I-R, and (5) I-R + ginger (I-R+G). To induce renal ischemia, animals were unilaterally nephrectomized and subjected to 45 min of left renal pedicle occlusion with 24 h reperfusion. Ginger was administered orally 24 h and just before ischemia. At the end of the experiment, blood samples and urine were collected. The following renal functional parameters were studied: serum and urinary levels of creatinine and urea, fractional excretion of sodium, and creatinine clearance. Histopathological examination of the kidney was also performed. RESULTS Rats with renal I-R showed a significant increase in creatinine and urea concentration in serum and also a significant decrease in creatinine clearance compared with the other groups. In addition, renal histopathology in the I-R group showed severe alterations such as tubular dilatation and tubular epithelial necrosis. However, these changes were significantly reduced in the I-R+G group. CONCLUSION This study suggests that ginger is a useful agent for the prevention of renal ischemia reperfusion-induced injury.

Abstract
Lymphadenitis with or without dry-type cutaneous leishmaniasis is rare. The lesion might self heal or show excellent response to antimonial therapy. Routine histopathological changes of localized leishmaniasis lymphadenitis are non-caseating to suppurative granulomata mostly in paracortical areas, some with extension to germinal centres, medullary cords and/or pericapsular spaces which have to be distinguished from other causes of lymphadenitis such as tuberculosis, cat-scratch disease and toxoplasmosis. Dense lymphoplasmocytic infiltrate was observed surrounding the necrotizing granuloma together with dense capsular fibrosis with multiple granulomata in subcapsular and pericapsular areas. Immunostaining of lymph nodes showed that a few macrophages were harbouring Leishman bodies. Dispersed Langerhans cells were also harbouring Leishman bodies in the parasitophorous vacuoles between their cytoplasmic pseudopods. In conclusion multiple noncaseating to suppurative granulomata with dense pericapsular and capsular granulomo-sclerotic changes should be considered in the differential diagnosis of leishmaniasis lymphadenitis.

Abstract
The skin lesions of five patient volunteers with dry-type cutaneous leishmaniasis were treated by intralesional injection of auto-leukocytes prepared from buffy coat of the patient's own blood. Giemsa stained, air-dried cytological smear preparations were prepared from scrapings taken from the margins of the lesions. The cellular interaction between the organism and the inflammatory response of the host was studied. All lesions showed clinical evidence of regression. The cytological findings suggested progressive degradation of the Leishman donovan (LD) bodies within the parasitophorous vacuoles of the activated macrophages. The parasiticidal effect appeared to be induced by synergistic action of the injected neutrophils and lymphocytes. Due to lack of placebo controls in this study the possibility that, healing might not be related to therapy can not be excluded. This study illustrates the potential for intralesional autotherapy with buffy coat in dry-type cutaneous leishmaniasis.

Abstract
Exfoliative cytology smears from the lesions of 179 patients with cutaneous leishmaniasis due to Leishmania tropica were studied with specific reference to cellular reactions and their effect on the parasite. Aggregates of the parasite (so-called Leishmania Donovan bodies) were present within macrophages and in some fibroblasts. The nature of the inflammatory reaction to the disease was studied by performing differential counts of the inflammatory cells present in the smears. These were correlated with the number of Leishman Donovan bodies. There was an inverse relationship between the number of Leishman Donovan bodies and the percentage of small lymphocytes, neutrophils, and type I macrophages. It is postulated that aggregates of activated macrophages (designated types II and III) and the Leishmanian milieu (sticky matrix) protect the amastigote Leishmania parasites from being eradicated by the inflammatory and immune reaction. The cytoplasmic blebbing of the parasitophorous vacuoles and cell to cell connection of the activated histiocytes could be shown by the CD-68 immunostaining of the tissue biopsy.
