Novi nalazi vodenih grinja (Acari, Hydrachnidia) iz materijala koji je sakupio u Hrvatskoj T. Petkovski, s popisom vrsta vodenih grinja iz Hrvatske

New records of water-mites from Croatia are given based on the material collected by T. Petkovski. Nine species are identified, four of which are new for the fauna of Croatia and one species is recorded for the first time in the Balkans. The ecological significance of the new records is briefly discussed.U radu se daju novi podaci o vodenim grinjama iz Hrvatske, temeljeni na materijalu koji je prikupio T. Petkovski. Određeno je devet vrsta, od čega su četiri nove za hrvatsku faunu, a jedna vrsta je zabilježena prvi put za Balkan. Kratko se raspravlja o ekološkom značaju novih podataka

The freshwater snails of the genus Bythinella Moquin-Tandon (Gastropoda: Rissooidea: Hydrobiidae) from Montenegro

New records of freshwater snails of the genus Bythinella Moquin-Tandon from Montenegro are presented. Bythinella dispersa, 1973 and B. luteola Radoman, 1976 are recognized and defined as separate species; B. taraensis n. sp., which lives partially sympatric with B. dispersa in the canyon of the River Tara, is described as new. All Bythinella spp. in Montengro inhabit the Dinaric part of the Black Sea drainage area, while it is practically absent from the Adriatic drainage area

Nueva especie of Separatoppia Mahunka, 1983 (Acari, Oribatida, Oppiidae) de la India

A new oribatid mite species of the family Oppiidae –Separatoppia indica n. sp.– is described from India. This species is morphologically most similar to Separatoppia concava Ermilov & Rybalov, 2013 (Ethiopia), but differs from the latter by length of interlamellar and notogastral setae and development of humeral processes. The genus Separatoppia Mahunka, 1983 is recorded for the first time from India and the Oriental region.Se redescribe una nueva especie de ácaro oribátido de la familia Oppiidae –Separatoppia indica n. sp.– de India. La nueva especie es muy similar morfológicamente a Separatoppia concava Ermilov & Rybalov de Etiopía, pero se diferencia de ella por la longitud de las setas interlamelares y notogastrales y el desarrollo del proceso humeral. Es la primera cira del género Separatoppia Mahunka, 1983 en India y en la región oriental

Impact of genetics on neoadjuvant therapy with complete pathological response in metastatic colorectal cancer: case report and review of the literature

Treatment of colorectal metastatic cancer is still challenging, despite recent improvements in chemotherapy. A genetic cancer profile, such as the KRAS (Kirsten rat sarcoma) gene status, plays a key role in individualized tailored therapy. Molecular targeted therapy added to neoadjuvant chemotherapy can achieve a better pathological response and prolong survival. Pathological complete response of colorectal cancer stage N is rare. A 47-year-old female patient presented with rectal adenocarcinoma and three liver metastases (cT3d/4, N2, M1). After seven cycles of Bevacizumab and CAPOX in neoadjuvant setting, we noted more than 70.0% regression of metastases and complete regression of the primary tumor. We performed low anterior resection of rectum and synchronous subsegmental resection of S3, because the other two lesions were not detectable. Pathology revealed complete response of the primary and also secondary tumors. After 8 months, diagnostic tests did not show any sign of recurrence and the remaining liver lesions disappeared. Colorectal cancer is a heterogeneous disease and it is necessary to identify patients who are at-risk of recurrence and suitable for neoadjuvant therapy. Genetic biomarkers play an important role in metastatic colorectal cancer treatment. Because of the mutated KRAS gene, Bevacizumab was added to cytotoxic therapy achieving a complete pathological response of primary tumor and metastasis. This case is unique because all reported cases with similar results, described staged surgery and one of reverse staged surgery, but with similar results. This neoadjuvant therapy has extra ordinary results for colorectal cancer stage IV and can help disease-free and long-term survival

First record of Erpobdella concolor (Annandale, 1913) (Hirudinida: Erpobdellidae) from Greece

Erpobdella concolor (Annandale, 1913) was recorded for the first time from a spring in the Peloponnese, Greece. This locality represents the westernmost spot of the species range known so far

New Finds of Tokophrya wenzeli (Ciliophora, Suctorea) a Commensal of Water Mites (Acari, Hydracarina) and Redescription of a Species

The article deals with investigations of suctorian species Tokophrya wenzeli Matthes et Stiebler, 1970 which was observed in waterbodies of Ukraine, Poland and Macedonia. New observations permit to precise the morphology of tentacles and show the variability of such sufficient characters of the species as morphology of basal plate, stalk and actinophores. The redescription of the species is also presented.Статья посвящена изучению суктории Tokophrya wenzeli Matthes et Stiebler, 1970, обнаруженной в водоемах Украины, Польши и Македонии. Новые данные позволили уточнить детали строения щупалец цилиаты, также оказалось, что важные для диагностики вида признаки, как строение базального диска, стебелька и актинофоров достаточно изменчивы. Приводится переописание вида

Arsenic removal from water using low-cost adsorbents: A comparative study

Inorganic arsenic removal from water using low-cost adsorbents is presented in this paper. Selective removal of As(III) and As(V) from water was performed with natural materials (zeolite, bentonite, sepiolite, pyrolusite and limonite) and industrial by-products (waste filter sand as a water treatment residual and blast furnace slag from steel production); all inexpensive and locally available. Kinetic and equilibrium studies were realized using batch system techniques under conditions that are likely to occur in real water treatment systems. The natural zeolite and the industrial by-products were found to be good and inexpensive sorbents for arsenic while bentonite and sepiolite clays showed little affinity towards arsenic. The highest maximum sorption capacities were obtained for natural zeolite, 4.07 mg As(V) g-1, and waste iron slag, 4.04 mg As(V) g-1
