fMRI Neurofeedback research employs many different control conditions. Currently, there is no consensus as to which control condition is best, and the answer depends on what aspects of the neurofeedback-training design one is trying to control for. These aspects can range from determining whether participants can learn to control brain activity via neurofeedback to determining whether there are clinically significant effects of the neurofeedback intervention. Lack of consensus over criteria for control conditions has hampered the design and interpretation of studies employing neurofeedback protocols. This paper presents an overview of the most commonly employed control conditions currently used in neurofeedback studies and discusses their advantages and disadvantages. Control conditions covered include no control, treatment-as-usual, bidirectional-regulation control, feedback of an alternative brain signal, sham feedback, and mental-rehearsal control. We conclude that the selection of the control condition(s) should be determined by the specific research goal of the study and best procedures that effectively control for relevant confounding factors.

Plum fruit fresh weight (FW) estimation is crucial for various agricultural practices, including yield prediction, quality control, and market pricing. Traditional methods for estimating fruit weight are often destructive, time-consuming, and labor-intensive. In this study, we addressed the problem of predicting plum FW using artificial intelligence (AI) methods based on fruit dimensions.

This study evaluated the association between dental infection and maxillary sinus pathology, and the influence of age, sex, type of tooth, root proximity to the sinus floor, the condition of the primary maxillary ostium, and the presence of an accessory maxillary ostium in this process. Computed Tomography scans were selected, and upper posterior teeth were evaluated for the presence of apical periodontitis (AP), bone loss with furcation involvement, and endoperiodontal lesion (EPL), subsequently, sinuses were evaluated for mucosal thickening (MT) and opacification of the maxillary sinus (OMS). Logistic regression models were constructed, and Chi-squared and Fisher's tests were applied.

Periodontitis, a common chronic inflammatory condition caused by bacteria, leads to loss of attachment, resorption of alveolar bone, and ultimately tooth loss. Therefore, reducing bacterial load and fostering alveolar bone regeneration are essential components in the treatment of periodontitis. In this study, we prepared smaller-sized Ag-Metal Organic Frameworks (Ag@MOF) and loaded with sodium alginate (Alg) hydrogel for periodontitis treatment.

To determine longitudinal changes in the peripapillary retinal nerve fiber layer (pRNFL) thickness in type 2 diabetes mellitus (T2DM) patients with hypertension (HTN). Participants were divided into three groups: normal controls (Group 1), patients with T2DM (Group 2), and patients with both T2DM and HTN (Group 3). Following the initial examination, patients underwent three additional examinations at 1-year intervals.
