Abstract
BACKGROUND Various surgical approaches have been employed to manage gingival recession, including subepithelial connective tissue grafting, which has yielded favorable outcomes. METHODS AND RESULTS We present the case of a 17-year-old patient who developed gingival recession on tooth #6 following an esthetic crown lengthening procedure. The recession was treated with a subepithelial connective tissue graft; however, this case details the occurrence of two epithelial cysts adjacent to the region subjected to the surgical procedure, 6 months after surgery. The treatment involved periodontal surgical intervention, during which the lesions were completely excised and the associated osseous defect was filled using an inorganic bovine bone matrix along with a collagen membrane. The healing progressed without any complications. Histopathological analysis revealed the presence of cystic lesions, which were characterized by a cystic cavity lined with stratified orthokeratinized epithelium with cuboidal cells in some areas surrounded by fibrous connective tissue. The patient's progress was monitored through tomography performed 6 months, 1 year, and 5 years post-procedure, all of which demonstrated the absence of any signs of lesion recurrence. CONCLUSION This case study emphasizes the effectiveness and predictability of subepithelial connective tissue grafting in the treatment of gingival recession. However, dental professionals should be cautious about the potential risk of gingival recession following esthetic crown lengthening procedures and recognize the potential complications associated with subepithelial connective tissue grafting, such as the observed development of epithelial cysts in this specific case. KEY POINTS Why is this case new information? We present a case of an epithelial cyst following a subepithelial connective tissue graft, which resulted in buccal cortical bone resorption. The treatment involved excisional biopsy and the use of an inorganic bovine bone matrix with a collagen membrane. What are the keys to the successful management of this case? Successful treatment included periodontal surgery, bone defect filling using an inorganic bovine bone matrix and a collagen membrane, and regular monitoring with CT scans at 6 months, 1 year, and 5 years post-surgery; all showed no recurrence. Success factors included careful surgery, appropriate biomaterial usage, and ongoing follow-up. What are the primary limitations to success in this case? The limitations involve potential complications from subepithelial connective tissue grafting such as cyst development. This report stresses the importance of meticulous patient selection and periodontal phenotype evaluation to minimize risks. Continuous follow-up is critical to detect recurrence and other issues.

Abstract
BACKGROUND Medicinal plants are an important source to identify new active pharmaceutical compounds. Traditionally, the sap of Euphorbia umbellata is widely used to treat cancer and inflammatory conditions. These effects have been attributed to the presence of terpenes and phenolic compounds in the extracts of this plant. Euphol, a tetracyclic triterpene alcohol, is one of the major compounds present in Euphorbia species, and some biological activities have been attributed to this compound. PURPOSE This study aimed to evaluate the in vitro cytotoxicity of euphol against Jurkat, HL-60, K-562, B16F10, and HRT-18 cells lines, as well as the biological stability, distribution, metabolism properties in vitro, and the determination of the concentration of euphol in the plasma and liver of rats. METHODS The MTT reduction assay was used to evaluate the cytotoxicity of euphol against cancer cell lines, and the selectivity index, the morphology and cell cycle assays to evaluate the death mechanisms in K-562 and B16F10 lineages. UHPLC-MS was applied for the in vivo evaluation of the concentration of euphol in plasma and liver, and in vitro metabolic stability in human liver microsomes and S9 fraction, plasma protein binding, and stability in simulated gastric and intestinal fluids assays. CONCLUSIONS This study demonstrated that euphol exhibited cytotoxic effects against a variety of cancer cells lines, selectivity against leukemia and possibly, the mechanism involved is apoptosis. The evaluation of stability, distribution, and metabolism properties showed that euphol was unstable in gastric and intestinal fluids, presenting moderate plasma protein binding with two hours elimination half-life and possible phase II liver metabolism. All the results suggested that further studies could be developed to prove the viability of euphol as an anticancer agent.

Abstract
BACKGROUND The thrips Frankliniella schultzei is an important watermelon pest. Nevertheless, economic injury levels and sampling plans for this pest have not yet been determined for this crop. Thus, the objective of the present study was to determine the economic injury levels and develop sequential sampling plans for F. schultzei in conditions of low, medium and high fruit prices. RESULTS The attack of F. schultzei on watermelon plants at the vegetative stage reduced the crop's productivity, which did not happen at the flowering and fruiting stage. The economic injury levels were 0.09, 0.04 and 0.02 thrips leaf-1 when the watermelon price was low ($US 62.5 t-1 ), medium ($US 140.63 t-1 ) and high ($US 218.75 t-1 ) respectively. The three sequential sampling plans for F. schultzei generated for the economic injury levels resulted in similar and more rapid decisions compared with the conventional plan, especially when the pest density was high. CONCLUSIONS The three economic injury levels and the sequential sampling plans generated in the present study can be incorporated into integrated pest management programmes for watermelon crops because these plans provide a rapid and adequate control decision for F. schultzei. © 2016 Society of Chemical Industry.
