Continuous evaluation of the policies and interventions could explore their efficacies in improving the accessibility and availability of medicines in the local market. This study explained the health system policies of the Islamic Republic of Iran concerning the impact of the economic sanctions on the local pharmaceutical market and addressed the issue of whether these policies were able to improve patients' access to medicines.
In this study, qualitative and quantitative research methods were used. In the qualitative part, semi-structured interviews with pharmaceutical system experts were used. In the next step, the structural analysis method was used. In the quantitative part, numerical sales data of the selected medicines were extracted and analyzed.
Reported statistics regarding the presence of the medicines in the market indicates the obvious fluctuations in the numerical sales of medicines in the studied years. This may indicate that the policies implemented are not able to fully compensate for the negative effects of sanctions and improve access to medicine. In addition, according to some experts, policy, and management weaknesses are mainly rooted in unresolved domestic hurdles which have exacerbated the effects of international sanctions on the country's pharmaceutical market.
Effective policy-making in response to economic sanctions can reduce the negative effect of international sanctions and result in drug shortages. Results of this study showed despite efforts made by the Iran health sector to subside the impact of sanctions on the pharmaceutical sector, there is an obvious disruption of the medicine supply chain in the market.

MicroRNAs (miRNAs) are small non-coding RNA molecules acting as critical regulators of post-transcriptional gene expression. MiR-33a and miR-122 have a crucial role in cholesterol and lipid metabolism. Therefore, their dysregulation may contribute to metabolic abnormality and their inhibition may be a useful therapeutic strategy. The objective of the present study was to investigate the relationship between miR-33a, miR-122, erythrocyte membrane fatty acids profile, and serum lipids with components of metabolic syndrome in an Iranian population suffering from type 2 diabetes mellitus (T2DM).
Expression of miR-33a and miR-122 was measured by real-time polymerase chain reaction and erythrocyte membrane fatty acid profiles were analyzed by gas chromatography-mass spectrometry.
T2DM patients with and without metabolic syndrome had significantly higher miR-33a and miR-122 levels compared to controls. MiRNAs were significantly correlated with saturated fatty acid (SFAs), total SFAs/total polyunsaturated fattypies may be explored as a potential therapeutic strategy.
Previously, we reported the anti-inflammatory properties of
(watercress) in several models of acute inflammation. This study was designed to explore the effects of topical and systemic administrations of
in the two chronic inflammatory models and to evaluate the role of TNF-α and IL-1β in these effects.
Folin-Ciocalteu and aluminum chloride methods were used to estimate the extract's total phenol and flavonoid content, respectively. Carrageenan-induced paw edema was carried out and TNF-α and IL-1β concentrations in the carrageenan-treated paw tissue were determined. Formalin injection into rat hind paws (7 days) and the application of 12-O-tetradecanoyl phorbol-13-acetate (TPA) on mouse ears (9 days) were used to simulate chronic inflammation. Furthermore, a histological assessment of the inflamed tissues was carried out.
The extract's flavonoid and phenolic contents were 90.26 ± 4.81 mg rutin equivalents/g and 68 ± 8.16 gallic acid equivalents/g gallic acid, respectively.
pretreatment in all doses administered considerably decreased carrageenan-induced edema. The extract also reduced IL-1β levels in carrageenan- treated paws while did not affect TNF-α levels. Oral and topical administrations of
considerably reserved the paw and ear edema. The extract also ameliorated the tissue injuries due to formalin and TPA challenges.
The data confirmed the topical and systemic anti-inflammatory effects of watercress against two chronic models of inflammation. They suggested that these properties are not related to TNF-α but could be attributed to inhibition of IL-1β and inhibition of leukocyte infiltration.

Ovarian cancer is one of the leading causes of cancer mortality in women. Despite the increase in cases of this cancer, the current therapeutic strategy is not effective. This study aimed to investigate the effect of cisplatin (Cis) with alantolactone (ALT) and ZnO nanoparticles (ZnONPs) in inducing apoptosis in SKOV3 ovarian cancer cells line.
To evaluate the viability of SKOV3 cells and determine the IC
of Cis, ALT, and ZnONPs, MTT assay was used. Real-time PCR and western blotting were used to evaluate the expression levels of genes (XIAP, cyclin D1, Bcl-2, Bax, and MDM2) and proteins (XIAP, cyclin D1, Bcl-2, Bax), respectively. Also, cellular ROS levels were assessed by fluorimetry.
Our results showed that ALT and ZnONPs significantly increased the response to Cis in SKOV3 cells compared to the control and this response is remarkably increased in the triple combination (ALT-Cis-ZnONPs). The expression of XIAP, cyclin D1, and Bcl-2 genes and proteins in the groups treated with ALT, Cis, and ZnONPs as a single agent, double and triple combination were significantly reduced compared to the control, while Bax was generally shown an increase. Also, the level of intracellular ROS is higher in the treatment groups than in the control group and the highest increase was observed in the triple combination.
Taken together, our data demonstrated the potential therapeutic approach of using ALT and ZnONPs that may enhance the apoptotic effects of Cis on the SKOV3 cells.

This study aimed to determine the potency of kebar grass ethanol extract to overcome an increase in cerebellar neuronal cell necrosis, which has an impact on decreasing motor reflex function and spatial memory of mice from lactating mothers exposed to carbofuran.
Forty lactating mice were divided into four groups, 10 each; including control, T1 (carbofuran 0.0125 mg/day), T2 (vitamin C 5 mg + carbofuran 0.0125 mg/day), T3 (kebar grass extract 3.375 mg + carbofuran 0.0125 mg/day). The mice were orally administered with carbofuran, vitamin C, and kebar grass extract on days 0 to 14 postnatal. On the 15
day, brains of the mice were necropsied to measure the levels of malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione (GSH), H&E staining; motor reflex tests were performed on 10-day-old mice, and the mice aged 30 days were tested on their swimming and spatial memory.
Carbofuran caused an increase in MDA, GSH, neuronal cell necrosis, surface righting reflex, a decrease in SOD, swimming ability, and spatial memory. Kebar grass extract and vitamin C administration decreased MDA, GSH, neuron necrosis, surface righting reflex, and increased SOD, swimming ability, and spatial memory.
Exposing to carbofuran in lactating mice caused brain oxidative stress, impaired motor reflexes, and spatial memory in mice offspring. Kebar grass extract and vitamin C administration prevented brain oxidative stress and inhibited disorders in motor reflexes, and spatial memory in mice offspring. Kebar grass extract administration was more effective than vitamin C.

Peripheral neuropathy is one of the most common adverse effects of cancer chemotherapy. Vincristine is prescribed to treat a variety of carcinomas, including lymphoma and leukemia, and may cause progressive peripheral neuropathy due to the damage of microtubules and mitochondria of neurons and affects inflammatory processes. This study was designed to evaluate the effects of
hydroalcoholic extract (LHE) of aerial part on vincristine-induced peripheral neuropathy in a rat model.
Neuropathy was induced in rats by daily intraperitoneal administration of vincristine (0.1 mg/kg for 2 weeks). Following the induction of neuropathy, animals were treated with the LHE (100, 200, and 400 mg/kg, p.o.) or pregabalin (20 mg/kg, IP) for 2 weeks, and their responses to vincristine-induced hyperalgesia and locomotor impairment were measured.
LHE, at the dose of 400 mg/kg, showed analgesic effects in response to thermal hyperalgesia, tactile allodynia, and gait impairment. Also, pregabalin (20 mg/kg, IP) improved the symptoms of vincristine-induced peripheral neuropathy.
According to the results, we can conclude that LHE alleviates neuropathic symptoms of vincristine and the effect is probably related to the presence of phenols and flavonoids in the extract.

Growth hormone (GH) has been known as a crucial metabolic hormone expressed at the pituitary and the other number of cells and tissues and responsible for body growth. Because of the short half-life of GH, daily subcutaneous injections were shown to be more effective for GH therapy. This represents a burden for patients. Lorlatinib ALK inhibitor So, there is a strong effort from the industry to create a long-acting form of GH and lots of technologies like GH fusion proteins are used to increase GH half-life.
In this study, the Fc domain of human IgG1 with serine-glycine linkers was attached to the C-terminal of a GH superagonist
molecular cloning. The presence of recombinant vector in
host was confirmed by PCR. SDS-PAGE and western blot analysis showed the expression of recombinant proteins in the bacterial lysate. The binding ability to growth hormone receptors is determined by ELISA.
Our results showed that the novel SupGH-Fc has a good binding affinity to its receptor in ELISA in comparison to standard GH, although it has a big size.
Our data in this study clearly demonstrated the expression of the SupGH-Fc in a recombinant protein expression system. It is an introduction to the production of the new recombinant GH, which can bind to its receptor more effectively than commercial growth hormones and also might have a longer half-life.
