OBJECTIVE:
To investigate the effect of M3P (containing Deer antler, Cordyceps sinensis, Rhodiola rosea, and Panax ginseng); an herbal remedy with the function of tonifying Kidney (Shen) and invigorating Spleen (Pi), replenishing qi and nourishing blood; on fatigue alleviation, endurance capacity and toxicity.
METHODS:
Swimming with weight-loading of 24 male ICR mice was used to evaluate the endurance capacity, and fatigue-related plasma biomarkers were determined. Mice were randomly assigned to control or M3P treatment groups with 6 mice for each group and were orally administered with M3P everyday for 8 weeks at doses 0, 10, 33 or 100 mg/kg. Swimming time to exhaustion was measured in a specialized water tank. Lliver and kidney functions, body weight, and hematological profile were determined to evaluate the safety and toxicity after long-term M3P administration.
RESULTS:
M3P supplementation 100 mg/kg significantly increased swimming endurance time up to approximate 2.4 folds of controls (P<0.05). The plasma concentrations of cortisol and hepatic glycogen content were significantly increased in mice received M3P (P<0.05, P<0.01 respectively). The lactic acid level and blood glucose were not changed after M3P treatment (P>0.05). The liver and kidney functions muscle damage biomarker creatine, body weight, and hemograms were not altered in M3P supplementation (P>0.05).
CONCLUSION
M3P supplementation may improve swimming endurance accompanied by increasing hepatic glycogen content and serum cortisol level without major toxicity.

To investigate the relationship of biofilm-forming ability of (PA) with swimming motility, twitching motility and virulence gene distribution. A total of 192 clinical isolates of PA were collected consecutively. Microtiter plate method was used to evaluate the ability to form biofilm. The swimming and twitching motilities were detected by plate method. Polymerase chain reaction (PCR) was used to detect virulence genes. Of the 192 PA clinical isolates, 186 (96.9%) showed biofilm-forming ability. Among them, 36 isolates showed weak biofilm-forming ability, 84 exhibited moderate biofilm-forming ability and 66 showed strong biofilm-forming ability. The diameters of the swimming ring for PA with none biofilm-forming ability, weak biofilm-forming ability, moderate biofilm-forming ability, strong biofilm-forming ability were (9.12±6.76), (18.42±7.51), (19.10±4.77) and respectively. The diameters of the twitching ring for PA in above groups were (8.38±1.50), (17.21±7.42), (18.49±5.62) and respectively. The swimming motility and twitching motility of none biofilm-forming ability group were weaker than biofilm-forming ability groups (all <0.05). Among 192 PA strains, 163 were positive (84.9%), 40 were positive (20.8%), 183 were positive (95.3%), and 189 were positive (98.4%). The positive rate of PA virulence gene , and were different in strains with different biofilm-forming abilities (<0.05). The rate of in the strong biofilm-forming ability group was lower than that in the moderate biofilm-forming ability group (=9.293, <0.01) and the weak biofilm-forming ability group (=9.997, <0.01). The rate of in the strong biofilm-forming ability group was higher than that in the weak biofilm-forming ability group (=10.803, <0.01). Most clinical isolates of PA can form biofilm. Swimming and twitching motilities are related to the formation of biofilm, but not significantly related to strength of biofilm-forming ability. The virulence genes of type Ⅲ secretion system for PA may be related to the biofilm-forming ability.

OBJECTIVE:
To explore the pathogenic role of changes of Wnt/β-catenin signaling pathway in the hippocampus in depression- and anxiety-like behaviors caused by prenatal stress (PS) in offspring rats.
METHODS:
Twelve female SpragueDawley rats weighing 240-260 g were randomly divided into control and restraint stress groups. The rats in the control group received no interventions, and those in restraint stress group were subjected to restraint stress (three times a day, 45 min each time) at the gestational age of 14-20 days. The 1-month-old offspring rats underwent open field test and forced swimming test to assess the anxiety- and depression-like behaviors, and the expressions of Wnt1, Gsk-3β and β-catenin in the hippocampus were detected using Western blotting.
RESULTS:
In open field test, the offspring rats with PS showed significantly decreased crossings of the center ( < 0.01) with reduced time spent in the center ( < 0.05) compared with control offspring rats. In forced swimming test, the offspring rats in PS group exhibited a significantly longer immobility time than in the control rats, and showed obvious depression- and anxiety-like behaviors. Compared with those in the control offspring rats, Gsk-3β expression increased significantly while the expressions of β-catenin and Wnt1 were significantly lowered in the hippocampus of the offspring rats in PS group ( < 0.01).
CONCLUSIONS
PS causes changes in Wnt/β-catenin signaling pathway in the hippocampus to contribute to the occurrence of depression-and anxiety-like behaviors in rats.

Acanthamoeba, one of free-living amoebae (FLA), remains a high risk of direct contact with this protozoan parasite which is ubiquitous in nature and man-made environment. This pathogenic FLA can cause sight-threatening amoebic keratitis (AK) and fatal granulomatous amoebic encephalitis (GAE) though these cases may not commonly be reported in our clinical settings. Acanthamoeba has been detected from different environmental sources namely; soil, water, hot-spring, swimming pool, air-conditioner, or contact lens storage cases. The identification of Acanthamoeba is based on morphological appearance and molecular techniques using PCR and DNA sequencing for clinico-epidemiological purposes. Recent treatments have long been ineffective against Acanthamoeba cyst, novel anti-Acanthamoeba agents have therefore been extensively investigated. There are efforts to utilize synthetic chemicals, lead compounds from medicinal plant extracts, and animal products to combat Acanthamoeba infection. Applied nanotechnology, an advanced technology, has shown to enhance the anti-Acanthamoeba activity in the encapsulated nanoparticles leading to new therapeutic options. This review attempts to provide an overview of the available data and studies on the occurrence of pathogenic Acanthamoeba among the Association of Southeast Asian Nations (ASEAN) members with the aim of identifying some potential contributing factors such as distribution, demographic profile of the patients, possible source of the parasite, mode of transmission and treatment. Further, this review attempts to provide future direction for prevention and control of the Acanthamoeba infection.

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by severe thunderclap headache with multifocal segmental vasoconstriction of the cerebral arteries. RCVS can be diagnosed if the cerebral angiogram shows segmental stenosis and spontaneously resolves within weeks to months. RCVS is reversible, but might cause brain lesions such as subarachnoid hemorrhage or cerebral infarction. We report a 45-year-old woman with severe sudden onset frontal headache who was identified with reversible cerebral vasoconstriction syndrome.

Waterborne parasitic protozoa, particularly Giardia lamblia and Cryptosporidium spp., are common causes of diarrhea and gastroenteritis worldwide. The most frequently identified source of infestation is water, and exposure involves either drinking water or recreation in swimming pools or natural bodies of water. In practice, studies on Cryptosporidium oocysts and Giardia cysts in surface water are challenging owing to the low concentrations of these microorganisms because of dilution. In this study, a 3-year monitoring of Cryptosporidium parvum, Giardia lamblia, and Naegleria fowleri was conducted from August 2014 to June 2016 at 5 surface water sites including 2 lakes, 1 river, and 2 water intake plants. A total of 50 water samples of 40 L were examined. Cryptosporidium oocysts were detected in 22% of samples and Giardia cysts in 32%. Water at the 5 sampling sites was all contaminated with Cryptosporidium oocysts (0–36/L), Giardia cysts (0–39/L), or both. The geometric mean concentrations of Cryptosporidium and Giardia were 1.14 oocysts/L and 4.62 cysts/L, respectively. Thus, effective monitoring plans must take into account the spatial and temporal parameters of contamination because they affect the prevalence and distribution of these protozoan cysts in local water resources.
