Dental composite resin is the preferred material for direct restoration due to its excellent mechanical and optical properties. However, adverse reactions caused by dental composite resins are not uncommon, and the main reason may be related to residual monomers that cannot be completely converted into polymers, and the resin polymers can be degraded and become degradation products in the oral environment. Residual monomers and degradation products can cause inflammation and allergic reactions, and even lead to body damage. This paper reviews the inflammatory and sensitization of dental composite resin.

Dental implants have become the primary choice for repairing patients with tooth loss. The material used for implants has mostly been titanium and titanium alloys. These materials are known to have excellent mechanical properties and biocompatibility. However, the surface of titanium implants is easily invaded by pathogens, and infection is infected after implant surgery. After infection occurs around the implant, the alveolar bone is progressively destroyed, which in turn causes the implant to loosen and ultimately fall off. Therefore, there is a dire need for effective preventive measures to reduce the risk of implant-related infections. This article will systematically review passive antifouling anti-biofouling strategies, active bactericidal surface bactericidal modification strategies, and targeted dissipation strategies after biofilm formation, which is aimed at preventing implant infection. This article will systematically review passive antifouling strategies, active bactericidal surface bactericidal modification strategies, and targeted dissipation strategies after biofilm formation, which are all aimed at preventing implant infection.

This paper will try to analyze the institutional authority disputes of the Democratic Republic of Timor-Leste. The legal study here is intended to describe law or legal science through a conceptual perspective approach and legislation approach, using constitutional theory and authority theory to justify an existing problem. The state sovereignty body, although its authority has been regulated in the 2002 RDTL constitution, in carrying out its duties and functions, each maintains its authority given by the constitution, a dispute over authority arises between the institutions of the President, the Government, the National Parliament, and the Court.

Sezary syndrome (SS) is a rare subtype of cutaneous T-cell lymphoma (CTCL) marked by erythroderma, circulating neoplastic T cells, and poor prognosis. Its belongs to the group of non-Hodgkin's lymphomas (NHL) resulting from malignant proliferation of skin-homing T cells. We report through a series of 6 cases, the experience of the hematology laboratory in the diagnosis of the syndrome of Sezary. Methods: This is a retrospective study of 6 cases of Sezary syndrome collected in the dermatology and hematology Departments Mohammed VI University Hospital of Marrakech. Results: six patients were identified with the clinicopathological criteria of SS. At the time of diagnosis, 5 patients had erythroderma and generalized lymphadenopathy in both superficial and deep stations. The white blood cell count was elevated (>10,000 WBC/mm3) in 3 patients. The blood smear showed the presence of small to medium-sized cells with a high nucleo-cytoplasmic ratio and cerebriform nuclei typical of Sezary cells and suggests the diagnosis of SS in all cases. Conclusions: The diagnosis of SS remains a challenge in many situations; the pathophysiology and definition of SS have evolved significantly over the past decades.

Power quality problem is an occurrence manifеstеd as an nonstandard voltage, currеnt or frequency that results in failure of еndusе еquipmеnts. Onе of thе major problеm in powеr quality is voltagе sag. To improvе thе powеr quality, custom powеr dеvicеs arе usеd. Thе custom powеr dеvicе usеd hеrе is SAPF (Shunt active power filter) is rolе to compеnsatе load voltagе during thе diffеrеnt fault conditions likе voltagе sag, singlе linе to ground, doublе linе to ground faults. In this work, PI controllеr and discrеtе PWM pulsе gеnеrator arе usеd for thе control purposе.

This study considered data on allocation of loans to all Nigerian states by the federal government from 2017 to 2021. It considered the value of guaranteed loans and number of fully paid loans as the independent variables and number of guaranteed loans as dependent variable. The system generalized method of moments (SGMM) was employed while investigating one-step and two-step method of estimations with linear and nonlinear moment conditions, namely; the one-step linear moment conditions (OSLMC), two-step linear moment conditions (TSLMC), one-step non-linear moment conditions (OSNLMC) and two step non-linear moment conditions (TSNLMC). The result shows that the OSLMC and OSNLMC method produced significant time-dummy coefficients that had predictive power, hence indicating that both could not portray the true representation of the relationship between the variables. Comparing the four methods TSLMC had valid instruments, significant coefficients with predictive power, significant time-dummy coefficients with no predictive power and model estimates with the least standard errors hence the best estimator. It is concluded that TSLMC method is most preferred compared to the OSLMC, TSNLMC and OSNLMC. Based on the best preferred model (TSLMC) the research reveals that the number of guaranteed loans given to any state in Nigeria is dependent on the guaranteed loan given to the state in the previous year with the value of the loan in the previous year and the current value of the loan.

The utilization of quantitative characters of pollen morphology from four species of Asteraceae and its taxonomic relevance was examined. Erdtman acetolysis method was adopted for analyzing fresh pollen samples from the four species. Light Microscope (LM) of X100 objective lens was used to take quantitative micromorphological features such as pollen size, wall thickness, number of pores, length of spines and number of colpi was done respectively. Single Linkage Cluster and ANOVA analysis were carried out to determine similarities and differences among the four species. Results showed insignificant differences in the variations that occurred for each parameter across the four species investigated at p>0.05. The similarities observed in the studied characters revealed inter-relationship existing among the four species, and thus lend credence to their present classification.
