Language is the gate of knowledge, without it, the humans will not be able to communicate with other people and will not be able to exchange ideas with others, because language is a communication mechanism between them to achieve their goals. Arabic is rich in legitimate vocabulary related to religion, so there are several vocabularies or words that cannot be understood only by knowing the meaning of language, so Arabic students must know the meaning of terminology words, because the terminology words include sentences that are rarely used in conversation, so the students get difficulty in using it in daily conversation, because the terminology words are included in the intellectual sentence. The purpose of this study is to make it easier for learners of Arabic to know the terms in the book of  Minhatu al 'Allam (fourth vol.) and help them choose vocabulary when speaking, writing, reading and listening. The study uses descriptive analysis methods, namely by tracing the terms in this book. This research proves the existence of the term sentence in the book of  Minhatu al 'Allam (fourth vol.). The term sentence reaches 53 words. This study also formulated effective ways to enrich the language of the STIBA Ar Raayah students, namely by making a term sentence table by explaining each term etymologically and terminologically, and presenting it in the form of daily conversation and writing.

The retroperitoneum can host a wide variety of pathologies, including benign and malignant tumors. Primary retroperitoneal tumors are rare, usually large in size, more than half of them being larger than 20 cm at the time of diagnosis, due to their silent growth. They often present several therapeutic challenges because of their rarity, relatively late presentation and anatomical location, often in close relationship with several important structures in the retroperitoneal space. Extensive surgery is often required because of the intimate relationships with vital organs in the retroperitoneum. Retroperitoneal sarcomas frequently involve major vessels, originating from them or secondarily encase or invade them, requiring major vascular resections, with increasing morbidity. The main intervention that can increase the survival of patients with retroperitoneal tumors is radical resection. The involvement of large retroperitoneal vessels often makes impossible a radical intervention, usually because of the lack of an adequate material for ample and laborious vascular reconstruction. In this paper, a thorough search of the PubMed database was performed, to bring into the light the implications of vascular involvement in primary retroperitoneal tumors and the need of a strong cooperation between the urological or general surgeon and the vascular surgeon.

Published: January 2020

We investigated the immunohistochemical expression of E-cadherin (product of CDH1 gene) and its correlation with clinical-pathological parameters and survival rate in the molecular groups of breast cancer. Our study included female breast cancer patients diagnosed at the Municipal Emergency Clinical Hospital Timisoara followed up five years since diagnosis using formalin fixed paraffin embedded tissue. The traditional prognostic factors (age, tumor size, histological type, histological grade, anatomical status of the lymph nodes) were abstracted from histopathology reports and we set prognostic index (the Nothingham and lymph-node prognosis index). Molecular classification on selected cases was performed in agreement with data from the literature: luminal A, B, HER2+, triple-negative. We noted positive (membranar) expressions in 43 cases (70.49 %). Negative immunoreactions for E-cadherin have been observed in all cases of lobular carcinomas (4 cases), as well as 6 cases of mixed carcinomas. A significant correlation was found between E-cadherin expression and hormonal status, tumor size, histologic type, tumor grade and molecular subtype. Most of the luminal A and B tumors were E-cadherin positive, while more than half of non-luminal tumors were E-cadherin negative. Survival rates are different in the negative and positive E-cadherin tumor groups respectively and between luminal and non-luminal groups. E-cadherin expression may be a useful prognostic marker for classifying other subgroups of breast cancer.

The purpose of this study was to investigate the sensorial, physico-chemical and nutritional traits of the meat in Flemish Giant rabbit breed. The biological material comprised 75 rabbits (25 males and 50 females), slaughtered at the age of 11 months, at an average carcass weight of 11.5 kg. Samples of the following muscle groups were taken: Longissimus dorsi (LD), Triceps brachii (TB) and Semimembranosus (SM) and were kept at 2 �C. Two hundred and twenty-five samples were analyzed to assess the physico-chemical peculiarities (pH measurements at 24- and 48 h post-slaughter; water, proteins, lipids, fatty acids and crude ash assessments). Another 225 samples (75 for each muscle group) were used as well to investigate the sensorial properties. The results issued from sensorial analysis were close as score among the three muscle groups studied. The pH value was higher in TB muscles. LD muscles from males had the highest protein content (21.70%), TB muscles of females had the highest proportion of lipids (2.65%), while the fatty acid content was higher in females for all analyzed muscles. Except for muscular content in some fatty acids, variance analysis highlighted not significant differences between genders for the studied characters.

Published: January 2020

The aim of this study was to use clonal gene rearrangements assays to discriminate between oligo-clonal or polyclonal reactive processes in cases that presented difficulty in diagnosis of B or T-acute lymphoblastic leukemia (ALL) due to abnormal phenotypes detected by flow-cytometry. Monoclonal B /T cells were detected by rearrangements of immunoglobulin (Ig) and T-cell receptors (TCR) in 10 patients. After DNA extraction from peripheral blood, multiplex PCR was used to amplify the Ig/TCR gene rearrangements followed by capillary electrophoresis, according to BIOMED 2 conditions. The evaluation of the results was carried out in the clinical and interdisciplinary (histomorphological, molecular and flow-cytometric) context. The presence of clonal rearrangements may indicate the existence of two neoplastic processes or a single clone with two gene rearrangements � one productive and one non-productive on the two alleles, considering the use of genomic DNA. By fragment analysis we identified B/T cells gene recombinations using multiplex PCR with primer sets that target each type of gene family. Using these molecular markers we can discriminate between monoclonal/polyclonal cells and follow a clonal marker throughout the disease evolution.

In the human body there is an endocannabinoid system consisting of cannabinoid receptors and endogenous transmitters - the endocannabinoids (anandamides).This cannabinoid system works by certain principles: the presynaptic neuron releases the neurotransmitter that reaches the postsynaptic neuron, activating it; at this level endocannabinoids are synthesized, whichhave retrograde transmission through the synaptic gap, reaching the cannabinoid receptors where they can inhibit the anterograde release of neurotransmitters. At the same level, certain exogenous substances, derived from plants and called phytocannabinoids may also work, the most known one being tetrahydrocannabinol. 9-D-Tetrahydrocannabinol is a component extracted from hemp plant with intense psychotic action but also with some medical applications. The result of the cannabinoid system activity is to obtain certain psychoactive effects, euphoria, relaxation, intense sensory experiences, pain relief but also changes in perception, attention deficit, etc. Synthetic cannabinoids are obtained to mimic the effects of marijuana, are major cannabinoid receptor agonists and are at increased risk of toxicity. Chronic consumption of such substances can cause memory disorders, pulmonary disorders and, most importantly, addiction.

Dorycnium herbaceum (DH) is a perennial herb or small shrub 10-80 cm high, which can be found in Central and Southeastern Europe. It is a little studied plant, which is known to have antibacterial and antifungal effect. In the present study we determined by spectrophotometric methods the total polyphenolic, flavonoidic, carotenic and chlorophyllic content of DH species, comparative to the bilberry. We also monitored the status of antioxidant enzymes using mice with oxidative stress induced by streptozotocinic diabet. For the induction of diabetes we used Swiss albino mice to which we injected streptozotocin intraperitoneally at a single dose of 180 mg / kg b.w.. The results showed that both chemical composition tinctures contain appreciable amounts of polyphenols, the highest content starring DH tincture species, but bilberry fruits have higher content of flavonoids, carotene and chlorophyll. Both plant extracts regulate the status of antioxidant enzymes, DH having superior efficacy.

Silicone, a synthetic polymer containing the element silicon, has been used for breast implants. Complications resulting from the placement of silicone breast implants are becoming more frequent in clinical practice. Breast implant rupture is common and poses challenges for radiologists and physicians. Radiologists must be familiar with the normal and abnormal findings of common implants. Clinically apparent silicone granulomas are a relatively rare complication of breast implant placement and surgical resection is indicated when they are symptomatic or of diagnostic concern. The objective of this study is to examine the latest generations of silicone breast implants and the clinical literature related to silicone granulomas together with a case of silicon granuloma diagnosed in our service. The findings are based on diagnostic breast Ultrasound and MRI scans performed at our service.

Published: January 2020

The visual evoked potentials technique records the cerebral bioelectric activity generated by light stimulation. Evoked potentials is a good method of assessing the electrical response of the brain to different stimuli and has been used extensively in the study of brain disturbances. We registered VEP on 18 hyperthyroid and 18 hypothyroid patients, without other endocrine, metabolic, ophthalmologic or neurological illnesses, the 2 groups having practically identical ages, but sex repartition, illness age and treatment duration being statistically different (p[0.001). Hormonal, radiological, biochemical dosages and physiological paraclinic determinations were performed on all 36 subjects, through classical methods, and VEP recordings, with a 4 channel polygraph through pattern reversal stimulation (1 Hz), measuring all parameters (latency, amplitude, duration, surface, steepness etc.) of N75 and P100 waves. Between groups, the recorded hormone levels and other recordings showed great differences, very highly statistically significant (p[0.001), only arterial pressures being just statistically significant (p[0.05). The Pearson�s r correlation coefficients indicated extremely high correlations (r=0.90-0.98) between all parameters. Between the 2 groups, hypothyroid patients had latencies of P100 wave higher with 17.88% (p=0.0028) and of the N75 wave with 9.98% (p=0.016), and the duration of the N75 wave lower with 26.37% (p=0.026), the other parameters of VEP waves modifying up to 52.35%, not statistically sgnificant due to high standard deviations. The duration of N75 correlates with the majority of humoral-paraclinical parameters, indicating a functional interdependency between them and the function of the cortex. The ratio of the amplitudes and of the areas of P100/N75 indicate a severe inhibition to hypothyroid patients, a precisely quantified reduction of the cerebral activity.

Authors: Gaman Mihnea Alexandru , Epingeac Mirela Elena , Gaman Amelia Maria
Published: January 2020

Diffuse large B-cell lymphoma (DLBCL) is the most common aggressive B-cell non-Hodgkin�s lymphoma. Oxidative stress, defined as an imbalance between the levels of pro-oxidants and the antioxidant defense, is involved in lymphomagenesis via chronic inflammation and is associated with a decrease in circulating levels of high-density lipoprotein (HDL) cholesterol. We evaluated oxidative stress levels in DLBCL patients by FORT (Free Oxygen Radicals Testing) and FORD assays (Free Oxygen Radical Defense), and investigated the relationship between oxidative stress markers and HDL-cholesterol levels. Our results suggest that oxidative stress and decreased levels of HDL-cholesterol might play a role in DLBCL pathogenesis via chronic inflammation.

The treatment of HTA plays a central part in the management of Chronic Kidney Disease (CKD) in all its stages, especially in patients following a substitute treatment of renal functions. HBP can be both the cause and the consequence of CKD. The HBP control in CKD patients represents one of the most important concerns of clinicians. HBP treatment is non pharmacological as well as pharmacological.

The treatment of chronic pancreatitis consists of conservative and surgical treatment. The current development of interventional endoscopy techniques links the two above-mentioned treatments, offering less invasive solutions. In the treatment of chronic pancreatitis, a progressive approach is needed. Establishing any type of treatment is useless if the patient does not follow the recommendation to mainatin a proper diet. The study was conducted on a group of 61 patientshospitalized and operated for chronic forms of pancreatitis. Pancreatic insufficiency due to chronic pancreatitis is not a simple enzymatic deficiency, but an interactive complex of secretory, motor and endocrine functional disorders. Therefore, developing drug therapy will require not only the simple administration of enzymes in the intestine but also the restoration of the integrity of disruptive digestive functions.

Hypertriglyceridemia is the most common etiology after alcohol consumption and gallstones. The risk of acute pancreatitis occurrence increases at a triglyceride level of over 1000 mg / dL. We hereby present a rare pathological situation of a young patient of 24 years old with acute, necrotic-hemorrhagic pancreatitis induced by hypertriglyceridemia. The emphasis is on the importance of considering the rare etiologies of acute pancreatitis and on the application of more effective treatments.

In the dental practice or in the ambulatory of oral and maxillo-facial surgery, there may be real medical emergencies, emergencies in which the speed of effective measures is essential. A good knowledge of the things to be done in the practice, as first representatives of the medical shield in defence against the inexorable secures the winning of precious seconds. Medical care in dentistry and dentoalveolar surgery involves two seemingly different aspects: a well-defined technical one, of strict specialty, and another less well defined, which practically includes all the particularities of the patient coming to the dental practice. However precise the dental technique and the practitioner�s skill are, if the specific conditions of each patient are not taken into account, the medical benefit cannot rise to a high level, and the final result may be compromised by complications with unforeseen risks. The study included 7,996 patients resolved in the Oral and Maxillo-facial Surgery Clinic (Ambulatory), in the period from 1.02.2014 to 31.12.2018. The superficiality of a seemingly healthy patient approach may lead to the disregard of some important aspects with a predictive role in the triggering of a medical emergency, as an informational history must be more than an orderly list of symptoms. You always gain something by listening to patients and observing the way they talk about their symptoms. The crossed statistical deductions on the explored data revealed, based on the majority percentages obtained on each studied index, that the following have an extremely important aspect for the dental practice and dentoalveolar surgery: the dental anxiety level as well as the patient�s general status are the landmarks that require the greatest attention from the practitioner for the purpose of preventing medical emergencies.

The objective was to determine the effect of in vitro fertilization (IVF) on nuchal translucency, free beta-human chorionic gonadotropin (Free b-HCG) and pregnancy-associated plasma protein-A (Papp-A) measurements for singleton and twin pregnancies. This was a retrospective population-based register study that included 2921women with 11-13 weeks of gestation singleton and twin pregnancies. All patients were evaluated for the first trimester Down syndrome combined screening. We identify the effect of assisted reproductive technologies (ART) such as in vitro fertilization (IVF) on the nuchal translucency (NT), free beta-human chorionic gonadotropin (b-HCG) and pregnancy-associated plasma protein-A (PAPP-A) values. The study included 2921 patients: 2526 with spontaneous conception (86.5%) and 395 following IVF (13.5%); in our study singleton pregnancies were 2660 (91.1%), dichorionic twin pregnancies 232 (7.9%) and 12 (0.4%) monochorionic twin pregnancies. The mean b-HCG were about 56.67 IU/l (95%CI: 54.98-58.36) in singleton pregnancies and 128.08 IU/l (95%CI: 115.72-140.45) in twin pregnancies. PAPP-A mean values in singleton pregnancies were 3.54 IU/l (95%CI: 3.42-3.66) and 5.25 IU/l (95%CI: 4.46-6.08) in twin pregnancies. The results were statistically significant with p value p�01. There were also significant differences between b-HCG values in spontaneous pregnancies HCG 63.35 IU/l (95%CI: 60.14-64.10) and IVF pregnancies HCG 99.9 IU/l (95%CI: 91.8-107.99) with p value p � 0.01. In our study the IVF had no impact on nuchal translucency values. Free b-HCG levels were higher in twin pregnancies and IVF pregnancies. PAPP-A concentrations were exceeded in twin pregnancies.

Uric acid is the end product of endogenous and exogenous of purine nucleotides catabolism, the serum concentrate being determined by the production and elimination ratio. Elimination is achieved through renal excretion � two thirds- and the rest through digestive way. In most studies, hyperuricemia is defined as ] 7 mg/dL uric acid in men and ] 6 mg/dL in women, and the guides for gout treatment recommend target value of uric acid under 6 mg/dL [1]. According to the NHANES ( National Health and Nutrition Examination Survey) register, the prevalence of hyperuricemia has increased by 3.2% and that of gout by 1.2% during the past twenty years[1].

Postoperative hypoparathyroidism is most commonly caused by the extirpation, injury or devascularisation of parathyroid glands. The aim of this study is to establish correlations between the advanced thyroid cancer staging, the appropriate individual treatment, the results obtained, the frequency and intensity of transient and/or permanent post-operative hypocalcemia. The present study can be continued with further researches in order to improve and develop surgical, oncological and endocrine management protocols for patients diagnosed with advanced thyroid cancer and also to avoid these relatively frequent and important complications.

This work is devoted to examine the effectiveness of the different commercial liquid additives for fish (sweet corn and molasses) on corrosion of mild steel in natural water by different methods (gravimetric and potentiostatic polarization) at room temperature. The corrosion tests were employed to evaluate corrosion rate (CR) and inhibition efficiency (IE %). The maximum inhibition efficiency was obtained for the inhibitor type molasses of 90.00% by gravimetric method for a period of 3 hours and over 31 % by potentiostatic polarization method. It was found that the commercial liquid additives acted as a good inhibitors for the tested environment. Furthermore, the corroded metal was observed by metallographic microscope.
