Study and optimization of freeze-drying cycles of a model probiotic strain
2018
This work is based on the experimental study of the freeze-drying process to understand the impact of numerous factors on the survival rates of a model probiotic strain of Lactobacillus casei type. With the aim to find out if cell density in the matrix and survival rates are linked, we have studied the location of the cells after freeze drying inside a porous matrix composed of a lactose basis with a polymer, the polyvinylpyrrolidone (PVP) in various amounts. The best survival rate were obtained at slow freezing rate for a formulation containing 5% (m/V) of lactose and 5% (m/V) of PVP. Keywords: Freeze-Drying; Freezing; Probiotics; L. Casei ATCC 393

Removal of Cypermethrin from Water by Using Fucus Spiralis Marine Alga
2019
Alpha-cypermethrin is a synthetic pyrethroid that was extensively used for insect control, since the early 1980s. However, it is known that its presence in the environment has toxic effects on humans and aquatic life forms. For this reason, it is commendable for it to be removed completely from the contaminated environment. In this study, we evaluated the adsorption capacity of a marine alga for the removal of cypermethrin from water. The adsorption experiments were performed based on the batch equilibrium technique. The samples containing the pesticide were analyzed using gas chromatography with an electron capture detector, after liquid-liquid extraction in hexane. The results obtained fr…
Appendiceal mucinous neoplasms: An uncertain nosological entity. Report of a case
2016
Introduction: Appendiceal mucocele is a relatively rare condition characterized by progressive dilation of the appendix caused by intraluminal accumulation of mucoid substance. Its incidence is 0.07 - 0,63% of all appendectomies performed. Case report: We report the case of a 70-year-old man who came to our observation with gravative pain in right lower abdominal region. A computed tomography abdominal scan revealed a cystic/tubular structure like an appendicular mass with wall enhancement but without calcifications suggestive of a mucocele. Into peritoneal cavity we found profuse mucinous material with a 1,5 cm size parietal nodule. We also identified a free perforation of the cecum with c…
Laparoscopic treatment of mesenteric avulsion and intestinal perforation after blunt abdominal trauma: A report of a case
2020
Highlights • Intestinal injuries are quite involved in non-penetrating abdominal trauma after liver and spleen. • The incidence of small bowel injury after blunt abdominal trauma has increased nowadays, since high-energy transfer impacts producing large abdominal wall displacements are more frequent, such as car crash. • We report a case of a 49-year-old Caucasian woman, victim of a violent car crash, resulting in multiple small bowel perforations and mesenteric avulsion treated with laparoscopic approach. • Laparoscopy is a safe and feasible tool in selected patients with blunt abdominal trauma, both for diagnosis and treatment. • The prerequisites for applying mini invasive approach are b…
Le «Facezie» di Poggio nel teatro spagnolo del “Siglo de oro”
2022
Un capitolo della fortuna europea del «Liber facetiarum» di Poggio Bracciolini riguarda le rielaborazioni e le riscritture di alcune di esse nelle commedie spagnole del secolo XVII (il cosiddetto “Siglo de oro”). In questo studio, dopo una preliminare ricognizione bibliografica sull’attuale status della ricerca sul «Liber facetiarum», vengono analizzati i modi di riscrittura di tre racconti del Bracciolini (fac. 157, 172, 203) in tre scene di commedie spagnole del XVII secolo, «La dama boba» ed «El perro del hortelano» di Lope de Vega e «Don Gil de las calzas verdes» di Tirso de Molina. A chapter of the European fortune of Poggio Bracciolini’s «Liber facetiarum» concerns the re-elaborations…
Latvijas Tautas frontes piemiņas plāksne
2020
Raksts izveidots, balstoties uz 2020. gada novembra mēneša priekšmetu. Mēneša priekšmets ir izvēlēts, aktualizējot 1991. gada Barikāžu 30 gadskārtu, skatoties LU vēstures kontekstā. Tiek analizēta un vērtēta LU loma LTF darbībā un tās cīņā par neatkarīgas Latvijas valsts atjaunošanu PSRS pēdējās pastāvēšanas laikā. Pielikumā rakstam nāk audio intervijas ar LTF LU nodaļas biedriem, kuri dalās savos pieredzes stāstos par vētrainajiem Trešās atmodas notikumiem LU un LU saimes attieksmi pret tiem.

Konstantīna Čakstes piemiņas plāksnes atklāšanas fotogrāfija
2023
Rakstā tiek skaidrota LU prof. Konstantīna Čakstes piemiņas tradīcijas uzsākšana LU, skaidrojot tā cēloņus (K. Čakstes kapavietas atklāšana), norisi (K. Čakstes piemiņas plāksnes atklāšana) un sekas (K. Čakstes piemiņas kopšana un tā labums LU Muzejam kā pētnieciskai atmiņu institūcija). Par raksta pamatu izvēlēta vēsturiska fotogrāfija, kurā attēlota K. Čakstes piemiņas plāksnes atklāšana, taču izmantots arī citu avotu un literatūras klāsts raksta sagatavošanā. Raksts sagatavots Latvijas valsts un LU 105 gadu jubileju ietvaros, kas mijas kopā ar pašreizējo starptautisko spriedzi - Krievijas-Ukrainas kara eskalāciju.
