REVIEW
Sonja Smiljic
Endocardial endothelium (EE) is essential in the embryonic development of the heart, the optimal contractility and rhythm as well as the remodeling of the heart. Endocardial endothelium affect the contractility of cardiomyocytes through paracrine signaling substances such as nitric oxide (NO), endothelin (ET-1), prostaglandins (PGI2, PGF2, PGE2) and angiotensin II (ANG II). Typical lesions of endocardial endothelium have been described in atrial fibrillation, ischemia/reperfusion injury, cardiac hypertrophy, heart failure, sepsis, myocardial infarction, inflammation and thrombosis...

BACKGROUND AND AIM: In 2013, all residency programs at the Lithuanian University of Health Sciences were renewed into the competency-based medical education curriculum (CBME). In 2015, we implemented the validated EFFECT questionnaire together with the EFFECT-System for quality assessment of clinical teaching in residency training. The aim of this study was to investigate the influence of characteristics of the resident (year of training) and clinical teacher (gender, age, and type of academic position) on teaching quality, as well as to assess areas for teaching quality improvement...

OBJECTIVE: The aim of this study was to evaluate feasibility and safety of stereotactic aspiration with fibrinolysis of deep-seated intracerebral hemorrhages (ICH). MATERIALS AND METHODS: From March 1995 until December 2016, 58 adult patients (34 men and 24 women; mean age of 56.8±11.8 years) presenting with deep-seated spontaneous supratentorial ICH were treated using a minimally invasive technique. Intracerebral hematomas were aspirated until obvious resistance to free-hand suction and subsequent clot fibrinolysis was done using either streptokinase or recombinant tissue-type plasminogen activator...

OBJECTIVE: The aim of this study was to test polymeric materials (collagen, fibrin, polyimide film, and polylactic acid) for single- and multi-layer scaffold formation. MATERIALS AND METHODS: In our study, we used rabbit bone marrow stem cells (rBMSCs) and human mesenchymal stem cells (hMSCs) with materials of a different origin for the formation of an artificial scaffold, such as a collagen scaffold, fibrin scaffold produced from clotted rabbit plasma, electrospun poly(lactic acid) (PLA) mats, polyimide film (PI), and the combination of the latter two...

BACKGROUND AND OBJECTIVE: Lithuania belongs to the group of countries with a high-incidence of tuberculosis (TB). Some scientific studies show that the interferon-gamma release assay is more accurate and correlates more highly with TB exposure as compared to the tuberculin skin test (TST). This study aimed at comparing the efficacy between the T SPOT TB and TST for diagnosing TB among Lithuanian adults. MATERIALS AND METHODS: Individuals with diagnosed TB, healthcare workers with known risk for TB and individuals without any known risk for TB underwent clinical examinations, interviews about their history of TB exposure and chest radiography...

BACKGROUND AND OBJECTIVE: The application of cytostatic oxazaphosphorines such as cyclophosphamide (CP) and ifosfamide (IF) is associated with the risk of kidney damage that, depending on the type of drug, dose and route of administration, adopts a different clinical entity and severity. The aim of our study was to assess the influence of CP and IF on the kidney histology and function in rats intraperitoneally treated with four doses of either CP or IF. MATERIALS AND METHODS: A total of 30 rats were divided into three groups (10 in each group): group 1 (control), sham treated with saline solution, group 2 (treated with 75mg/kg b...

Cardiovascular abnormalities are well-known manifestations of a late form of syphilis - tertiary syphilis. Since the era of antibiotics, the incidence of late manifestations of syphilis has declined almost to a rare entity. The injury of aorta (the aortitis with a dilatation of aortic root and its associated complications) is the most common between all the cardiovascular lesions. A less common manifestation of syphilitic aortitis is coronary artery ostial narrowing related to aortic wall thickening. We present the case of a 37-year-old male who was treated for an acute myocardial infarction due to bilateral coronary artery ostial stenosis secondary to syphilitic aortitis...

OBJECTIVE: The aim of this study was to compare the impact of treatment procedures on roots previously treated with resorcinol-formaldehyde resin and analyze the effectiveness of dye and magnification for the detection of dentin cracks. MATERIALS AND METHODS: Distal roots of 80 permanent first mandibular molars with a single canal were sectioned at 3mm and 9mm from the anatomical apex. Two groups were formed according to the method used for root canal penetration: group 1 (K-file and Pro Taper instruments) and group 2 (Ultrasound with Pro Ultra and Pro Taper files)...

BACKGROUND AND AIM: Alpha-tocopherol has been implicated in reproduction processes, and deficiency of phylloquinone has been associated with serious complications in pregnancy. This study was therefore aimed at investigating the effects of phylloquinone and alpha-tocopherol on uterine contractility and female reproductive function using mouse models. MATERIALS AND METHODS: Both in vivo and ex vivo animal models were employed and designed to assess changes on uterine contractility and reproductive functions in the non-pregnant uterus...

BACKGROUND AND AIM: Previous research has highlighted the role of self-rated health (SRH) as an important predictor of mortality. With substantial ethnic differences in SRH and mortality reported in Estonia, this study aims to examine the ethnic variation in SRH-mortality association in this setting. MATERIALS AND METHODS: The baseline data come from the nationally representative 1996 Estonian Health Interview Survey. Individual records of 3983 respondents in the 25-79 age group were linked with mortality data with 17 years follow-up time...

BACKGROUND AND OBJECTIVE: Infantile hemangiomas (IHs) are benign lesions found in infants. Predicting the cosmetic outcome of these lesions is very difficult. Therefore, in this prospective study, we assessed whether using an infrared thermometer (IRT) to measure the surface temperature of IHs would help to predict their proliferative potential. MATERIALS AND METHODS: Between January 2012 and March 2014, we prospectively investigated 103 children up to 6 months of age with a diagnosis of IH...

BACKGROUND AND OBJECTIVE: One of the main causes of bacterial resistance to antimicrobials is multidrug resistance induced by the increased efficiency of the efflux pumps. In this study we analyzed how the conditions of assay affect the efflux of indicator substrates ethidium (Et(+)) and tetraphenylphosphonium (TPP(+)) in Salmonella enterica ser. Typhimurium cells. Impact of the outer membrane permeability barrier, composition and temperature of the medium on accumulation of the indicator compounds also was analyzed...

REVIEW
Gintautas Grabauskas, Chung Owyang
Vagal sensory neurons mediate the vago-vagal reflex which, in turn, regulates a wide array of gastrointestinal functions including esophageal motility, gastric accommodation and pancreatic enzyme secretion. These neurons also transmit sensory information from the gut to the central nervous system, which then mediates the sensations of nausea, fullness and satiety. Recent research indicates that vagal afferent neurons process non-uniform properties and a significant degree of plasticity. These properties are important to ensure that vagally regulated gastrointestinal functions respond rapidly and appropriately to various intrinsic and extrinsic factors...

Vertebral hemangiomas are the most common benign vertebral neoplasms and are generally asymptomatic. In the present study, we report the case of a 52-year-old male master ultra-marathoner suffering from a pathologic fracture of the thoracic spine due to a vertebral hemangioma. A further examination in the athlete revealed an accompanying osteopenia, which was most likely due to a deficiency in both vitamin D and testosterone. The treatment of the fracture consisted of percutaneous vertebroplasty. Shortly after the operation the athlete was able to continue running...
