Thirty-four dogs suffering from severe babesiosis caused by Babesia canis rossi were included in this study to evaluate acid-base imbalances with the quantitative clinical approach proposed by Stewart. All but 3 dogs were severely anemic (hematocrit <12%). Arterial pH varied from severe acidemia to alkalemia. Most animals (31 of 34; 91%) had inappropriate hypocapnia with the partial pressure of CO2 < 10 mm Hg in 12 of 34 dogs (35%). All dogs had a negative base excess (BE; mean of - 16.5 mEq/L) and it was below the lower normal limit in 25. Hypoxemia was present in 3 dogs. Most dogs (28 of 34; 82%) were hyperlactatemic. Seventy percent of dogs (23 of 33) were hypoalbuminemic. Anion gap (AG) was widely distributed, being high in 15, low in 12, and normal in 6 of the 33 dogs. The strong ion difference (SID; difference between the sodium and chloride concentrations) was low in 20 of 33 dogs, chiefly because of hyperchloremia. Dilutional acidosis was present in 23 of 34 dogs. Hypoalbuminemic alkalosis was present in all dogs. Increase in unmeasured strong anions resulted in a negative BE in all dogs. Concurrent metabolic acidosis and respiratory alkalosis was identified in 31 of 34 dogs. A high AG metabolic acidosis was present in 15 of 33 dogs. The lack of an AG increase in the remaining dogs was attributed to concurrent hypoalbuminemia, which is common in this disease. Significant contributors to BE were the SID, free water abnormalities, and AG (all with P < .01). Mixed metabolic and respiratory acid-base imbalances are common in severe canine babesiosis, and resemble imbalances described in canine endotoxemia and human malaria.

A novel small molecule thiocarbazate (PubChem SID 26681509), a potent inhibitor of human cathepsin L (EC 3.4.22.15) with an IC(50) of 56 nM, was developed after a 57,821-compound screen of the National Institutes of Health Molecular Libraries Small Molecule Repository. After a 4-h preincubation with cathepsin L, this compound became even more potent, demonstrating an IC(50) of 1.0 nM. The thiocarbazate was determined to be a slow-binding and slowly reversible competitive inhibitor. Through a transient kinetic analysis for single-step reversibility, inhibition rate constants were k(on) = 24,000 M(-1)s(-1) and k(off) = 2.2 x 10(-5) s(-1) (K(i) = 0.89 nM). Molecular docking studies were undertaken using the experimentally derived X-ray crystal structure of papain/CLIK-148 (1cvz. pdb). These studies revealed critical hydrogen bonding patterns of the thiocarbazate with key active site residues in papain. The thiocarbazate displayed 7- to 151-fold greater selectivity toward cathepsin L than papain and cathepsins B, K, V, and S with no activity against cathepsin G. The inhibitor demonstrated a lack of toxicity in human aortic endothelial cells and zebrafish. In addition, the thiocarbazate inhibited in vitro propagation of malaria parasite Plasmodium falciparum with an IC(50) of 15.4 microM and inhibited Leishmania major with an IC(50) of 12.5 microM.

Medicinal plants that are used today have been known by people of ancient cultures around the world and have largely been considered due to their medicinal properties. Cornus mas L. (Cornelian cherry) is one of these medicinal plants with high level of antioxidant activity. Cornelian cherry is an attractive ornamental plant with delicious fruit having nutritional and therapeutic values. The main purpose of this paper is to present and summarize the pharmacological and therapeutic effects from researches done on Cornelian cherry in studies from 2000 to 2016. Information and findings in this review were taken from electronic journals in some websites including PubMed, Elsevier, ISI, Google scholar, SID and relevant books. C. mas L. is important in terms of decoration and is used in traditional medicine to treat diarrhea, inflammatory bowel disease, cholera, fever, malaria, kidney stones, urinary tract infections, cancer, bleeding and heat stroke. Several studies have shown that Cornelian cherry fruit plays an important role in prevention of atherosclerosis, blood sugar, lipid profiles and reduction of fat accumulation in the liver. Cornelian cherry has antimicrobial, antiparasitic, anti-inflammatory, antioxidant and anticancer effects as well as protecting liver, kidney and cardiovascular system. Using Cornelian cherry in pharmaceutical and food industries has caused fantastic value of this plant. Pharmaceutical properties of Cornelian cherry seeds, fruits, leaves and stems have led the need of further studies to explore the other unknown effects or review mechanism of its pharmacological effects for preparation of new drugs.

Climate is an effective factor in the ecological structure which plays an important role in control and outbreak of the diseases caused by biological factors like malaria. With regard to the occurring climatic change, this study aimed to review the effects of climate change on malaria in Iran. In this systematic review, Cochrane, PubMed and ScienceDirect (as international databases), SID and Magiran as Persian databases were investigated through MESH keywords including climate change, global warming, malaria, Anopheles, and Iran. The related articles were screened and finally their results were extracted using data extraction sheets. Totally 41 papers were resulted through databases searching process. Finally 14 papers which met inclusion criteria were included in data extraction stage. The findings indicated that Anopheles mosquitoes are present at least in 115 places in Iran; they are compatible with climatic zones of Iran. Malaria and it's vectors are affected by climate change. Temperature, precipitation, relative humidity, wind intensity and direction are the most important climatic factors affecting the growth and proliferation of Anopheles, Plasmodium and the prevalence of malaria. The transmission of malaria in Iran is associated with the climatic factors of temperature, rainfall, and humidity. Therefore, with regard to the occurring climatic change, the incidence of the disease may also change which needs to be taken into consideration while planning of malaria control.
