Palpebral ptosis is a condition caused by different congenital and acquired pathologies. Seeing difficulty due to the visual field obstruction, prefrontal headaches due to chronic use of the frontalis muscle in an attempt to lift the eyelids and cosmetic deformity are the main complaints of the patients. The surgical correction of the ptosis can be challenging. According to the preoperative evaluation, the most appropriate technique should be used to maximize the postoperator result. We describe a new surgical approach for severe upper eyelids acquired ptosis consisting in reanimation of both eyelids by using the neighboring active muscle. We considered the patient a good candidate for the new surgical approach we introduce as one time operative procedure. The result was a normal palpebral fissure for both eyes. The advantage of this approach consists in performing one time surgery followed by immediate postoperative mobilization of the upper eyelids which determine the recovery of the upper lids motility by further self-control.

There are many fixing and colouring substances largely used in the anatomy laboratories, for teaching purpose. We have injected 22 adult human hearts, removed from the cadavers belonging to the Anatomy and Embryology Department. On 6 specimens we have followed the embryologic myocardium structures for micro angio architecture studies. We used histological techniques like: haematoxylin-eosin, Van Gieson, and Masson‘s Trichrome methods. Also we have removed and dissected 14 kidneys and 16 anatomical structures of the peripheral nervous system: coeliac ganglia, aortico renal ganglia and mesenteric ganglia. The least were analyzed using specific techniques of the nervous system: Nissl method and Bielschowsky silver stain method. 8 foetuses (aged between 4 and 8 months of gestation) were dissected and also analysed. Our results were in according to the literature studies.

Synthetic polypropylene materials are increasingly being used in surgery to repair parietal defects in perineal floor curing surgery, in genital prolapse and stress urinary incontinence. The tissue response to contact with these materials varies, and the inflammatory tissue response may be a prognostic marker of success in surgical interventions that involve contact between tissues and polypropylene materials.

The aim of this paper was to present the method used for creating a 3D model of a fractured hemipelvis and its accuracy in reproducing dimensions and structural relationships between fractured fragments. A PolyLactic acid model of the hemipelvis was generated with the aid of the 3D printer. Using a 3D model of a complex fracture aids the orthopedic surgeon in planning the intervention and choosing the best fixation method. Patients with pelvic fractures are not usually operated immediately, which is why they can benefit from this technology.

Ureteral stents represent one of the most utilized medical device in urology, as a minimally invasive alternative to preserve urine outflow. The ideal ureteral stent which combines long-term efficacy with a very low rate of side effects is still missing from the urologist armamentarium. The main material for ureteral stents production is polyurethane. In order to improve the side-effects and complications of polyurethane stents, special coatings were developed. The aim of this study is to evaluate short-term side-effects and complications of different polyurethane stents with or without coating used in urologic field.

The bronchial stump fistula shown by patients undergoing adjusted pulmonary resections is an extremely severe condition affecting the prognosis of this patients. Within our study, we have used an innovative technique of closing the bronchial stump for 38 patients undergoing adjusted pulmonary resections. The suture of the bronchial stump was made through an innovative method, by practicing the suture with isolated 2.0 Prolene wires armed with patches of Polypropylene. The incidence of the bronchial stump fistula for the observed lot was of 5.26% (2 cases), smaller than the one reported in the specialty literature. In this respect, we consider that the use of Polypropylene in the techniques of closing the bronchial blunt can be beneficial.

Mesenchymal stem cells (MSCs) are increasingly being used in regenerative medicine to repair various tissue types. This study aimed to assess changes in MSCs properties as a result of their interaction with two biomaterials in order to evaluate their in vitro compatibility. We have used two types of biomaterials, as follows: hydroxyapatite anodized titanium (HA-Ti) is used in bone reconstruction; it is hard and remains in the body, while patches of collagen combined with poly-e-caprolactone (C-PCL) are utilized in the reconstruction of soft tissue (particularly the skin); these patches resorb in the body, being only a temporary matrix that fosters and accelerates tissue formation. We have chosen to assess changes in morphology, viability and proliferation of MSCs obtained by lipoaspirate, through direct contact with the biomaterial or in eluate. MSCs properties were assessed by optical microscopy, fluorescence microscopy after acridine orange/ethidium bromide (AO/EB) staining, and the MTT assay. After result interpretation, we gained an image of the cytotoxicity phenomenon seen during the experiment and were able to assess viability of cell in contact with the biomaterials used. HA-Ti shows better interaction with cells, which preserve their viability, and does not influence MSCs growth, proliferation or morphology. In contrast, cells on C-PCL matrix become small, spherical, were detached from the plate and had lower viability percentage.

The paper is focused on the comparison between the experimental test and numerical analysis of a composite panel wich is subject to plastic deformation. An experiment was done on a sandwich panel made from steel – extruded polystyrene – steel, wich was subjected to a static plastic deformation with help of an sferical indenter. During the test the force applied to the indenter and the vertical displacement of the steel panels were measured. The experimental values were compared with the results of numerical simulation, wich was done with help of ANSYS-Static Structural module. Important aspects of FEA, such as material idealization, contact approach between bodies, mesh size and boundary conditions, are discussed and their influence on the results are highlighted. The results of this study are vey useful for investigation of beahviour at impact of composite materials such as steel-polystyrene sandwich panels.

In this paper, we propose an analyzis method for the dynamics of polymer chains, based on a Ricatti procedure induced by possible correlations through the compatibility of the thermal radiation-classical damped oscillator dynamics. Then, the quantification (radiation frecquency is directly proportional to the color temperature) and the erasure of one bit of information becomes a natural processes induced by the system structure itself. The theory has implications in the dynamics of biological structures (arhitecture of tumors, information on tumor growth and angiogenesis, etc.) in the form of Resonant Recognition Model.

Patients with occupational lung diseases (OLD) may present respiratory functional impairment, exertional dyspnea and decreased exercise tolerance. These factors lead to reduced daily physical activity, social isolation, decreased quality of life (QoL) and depression. Assessment of respiratory functional status in patients with OLD in correlation with the presence of anxiety and depression and the quality of life in patients with OLD, as extrapulmonary comorbidities. In patients with diagnosed OLD, the following parameters were evaluated: pulmonary function tests (FEV1, FVC), anxiety and depression with Hospital Anxiety and Depression Scale (HADS), and QoL by St George Respiratory Questionnaire (SGRQ). 46 non-smoking patients (9 females) were included in this study: occupational asthma (10), occupational COPD (20), pneumoconiosis (16). Mean aged 58.98±11.84SD years old. Anxiety and depression were present in 35 patients (76.08%). Mean HADS score was 14.3 points±7.25SD, and a severe psychological impairment (HADS > 16) was found in 16 cases (34.8%). The highest incidence of anxiety and depression was found in COPD (85%, mean HADS score 16.05 points±8.18SD), followed by pneumoconiosis (75%, mean HADS 13.5 points±6.87SD) and OA (60%, mean HADS score 12.2 points±5.45SD). The QoL was affected in all patients, with a mean SGRQ score of 52.7 points±16.1SD; the most affected was the activity domain. In patients with OLD, extrapulmonary manifestations may be encountered, such as anxiety, depression and ultimately impaired QoL. This may indicate that treatment of these patients should be multidisciplinary, including psychosocial support.
