Abstract
The effects of in ovo lactoferrin (Lf) injection on some physiological parameters and immune response of posthatch chicks were investigated. Live embryonated Fayoumi chicken eggs (n = 600) were randomly allocated into four groups. The first group as a control was noninjected eggs, the second group was only injected with 0.1 mL of NaCl 0.75% solution, and the third and fourth groups were injected with 50 and 100 µL Lf dissolved in 0.1 mL saline solution respectively. The eggs were injected on Day 15 of incubation in the amnion. The results illustrated that the hatchability of eggs in two Lf groups was significantly higher than in the control, NaCl groups. The residual yolk in chicks injected with Lf (100 µL/egg) was significantly lower than the control group (p < 0.05). In ovo Lf injection improved lipid profile, liver function, antioxidant indices, blood haematology, serum immunoglobulins and jejunum histomorphometry compared to the control group (p < 0.05). In ovo injection of Lf decreased significantly (p < 0.001) of pathogenic bacteria in residual yolk such as Salmonella, Shigella and Coliform compared to the control group. In conclusion, in ovo Lf injection can improve the hatchability, lipid profile, immune response and antioxidant indices and decline pathogens in the residual yolk, thus boosting the health status of newly hatched Fayoumi chicks.

Abstract
Glyphosate is an ingredient widely used in various commercial formulations, including Roundup®. This study focused on tight junctions and the expression of inflammatory genes in the small intestine of chicks. On the sixth day of embryonic development, the eggs were randomly assigned to three groups: the control group (CON, n = 60), the glyphosate group (GLYP, n = 60), which received 10 mg of active glyphosate/kg egg mass, and the Roundup®-based glyphosate group also received 10 mg of glyphosate. The results indicated that the chicks exposed to glyphosate or Roundup® exhibited signs of oxidative stress. Additionally, histopathological alterations in the small intestine tissues included villi fusion, complete fusion of some intestinal villi, a reduced number of goblet cells, and necrosis of some submucosal epithelial cells in chicks. Genes related to the small intestine (ZO-1, ZO-2, Claudin-1, Claudin-3, JAM2, and Occludin), as well as the levels of pro-inflammatory cytokines (IFNγ, IL-1β, and IL-6), exhibited significant changes in the groups exposed to glyphosate or Roundup® compared to the control group. In conclusion, the toxicity of pure glyphosate or Roundup® likely disrupts the small intestine of chicks by modulating the expression of genes associated with tight junctions in the small intestine.

Abstract
This study aimed to evaluate the effects of in ovo injection of soy isoflavones (ISF) on hatchability, body weight, antioxidant status and intestinal development of newly hatched broiler chicks. One hundred and eighty fertile eggs were divided as follows: the control group, 3 mg/egg ISF (low dose) and 6 mg/egg ISF (high dose) on the 18th day of incubation. The results demonstrated that in ovo inclusion of 6 mg of ISF significantly increased hatchability and hatch weight. Both doses of ISF inclusion elevated the serum glutathione peroxidase and slightly decreased malondialdehyde compared to the control group. The high dose of ISF brings higher villus height and a higher villus/crypt ratio in chicks. Moreover, the mRNA levels of tumour necrosis factor- α and interferon-gamma in the spleen were significantly decreased. The ISF treatments showed an improvement in intestinal enzyme expression levels of sucrose isomaltase and mucin 2 as well as tight junction protein (TJ) mRNA expression of claudin-1 at high doses of ISF (p < 0.05) when compared with the other groups. Furthermore, the mRNA level of IGF-1 was increased in the high doses of ISF compared to the control. Overall, these findings indicate that in ovo administration of ISF on the 18th day of incubation enhances hatchability, antioxidant status and intestinal morphometrics in hatched chicks and modulates the expression of proinflammatory cytokines, TJs and insulin-like growth factor. In addition, the sustainability of antioxidants and other positive effects of ISF may increase chick viability and growth performance.

Abstract
Maltose tetrapalmitate (MTP), a synthetic nontoxic immunoadjuvant, the radiosensitizer misonidazole (MISO), and 60Co gamma-radiation, alone or in combination, were used in the management of Dunning prostatic tumor in the rat. Nine groups of 10 rats each were used to assess the efficacy of various therapeutic modalities. Tumor growth rates and animal survival times were determined for each group. Radiation was more effective when combined with MTP, but the adjuvant must be present when radiation is given for synergism to occur. MISO was as effective as MTP when used with radiation, but combining them cancels out their individual effects. In a clinical situation it would be advantageous to use separately the synergisms existing between MISO and radiation on the one hand and MTP and radiation on the other hand.

Abstract
The hypoxic-cell radiosensitizer misonidazole was administered intravesically to normal and to bladder tumor-bearing female Fischer rats. Drug concentration was measured in the bladder wall, the tumor and in the serum using high pressure liquid chromatography at different times following administration. The data shows that misonidazole is readily adsorbed by the bladder wall and the tumor with tissue levels reaching up to 10 times those measured in the serum.
